Coccygodynia

Coccydynia is pain in the coccyx (the small bone at the bottom of your spine). This small triangular bone is located at the very bottom of your back. This condition causes pain when you sit down and when you change position. It makes work, driving, and daily activities uncomfortable. If you are living with this pain, rest assured: coccydynia is treatable in the vast majority of cases. Physical therapy offers effective treatments. We use manual techniques, pelvic floor work, and lifestyle changes. We treat both the coccyx problems and their causes. Although coccydynia is specific to the coccyx, it is part of the range of back pain problems we treat. Understanding coccyx pain helps you distinguish it from other back problems. It also guides the right treatment for lasting relief.

What is coccydynia and where does it hurt?

Coccydynia is pain in the coccyx at the very bottom of your spine. The pain usually worsens when you sit down or get up from a chair. This condition affects the small triangular bone formed by 3 to 5 fused vertebrae below the sacrum (the triangular bone above the buttocks).¹

The coccyx is located just below the sacrum. In Quebec, it is also called the "little bone at the bottom of the back." This is where ligaments, tendons, and pelvic floor muscles attach. This includes the levator ani muscles (the muscles that support your pelvic organs).

You can point to the pain directly on the tip of the coccyx with your finger. This specific location helps distinguish coccydynia from other problems. Sacroiliac pain (the joint between the sacrum and the pelvis) is located higher up and on the side. Lumbar problems are located above the sacrum. This anatomical distinction is important for making the correct diagnosis. Women are about five times more likely to experience coccydynia than men.² This is because women have a different pelvic shape. Childbirth can also injure the coccyx. The female coccyx moves more and is located further back. This makes it easier to injure.

The coccyx supports approximately 2 to 10% of your body weight when you are seated.³ This is why sitting makes coccydynia worse. Understanding how the coccyx works helps you see that this pain is different from other types of back pain.

What causes tailbone pain?

Coccydynia often results from direct trauma. For example, falling on the buttocks, injury during childbirth, or sitting for long periods on hard surfaces. Other causes include repetitive sports such as cycling or rowing. Less common causes include infections, tumors, or referred pain from pelvic floor problems.

Falling on your buttocks creates sudden forces. They can break or injure the coccyx. Unlike lumbar sprains, which affect the ligaments in the lower back, coccydynia directly affects the coccyx bone. Childbirth can also injure the tailbone. This happens when the baby's head passes through the birth canal.⁵ Long or difficult labor increases the risk. This is even more true with large babies.

Activities that put constant pressure on your tailbone can cause chronic pain. Cycling, rowing, and horseback riding stress the tailbone. This happens every time you move and sit down. Sitting for long periods of time on hard surfaces without a cushion puts too much pressure on the tailbone.⁶ Jobs where you spend a lot of time sitting increase your risk.

Pelvic floor problems are a hidden but significant cause. The levator ani muscles attach to the coccyx. When these muscles are too tense or have trigger points (sensitive areas in the muscle), they cause pain. This pain is felt in the coccyx.⁷ This explains why some cases improve with pelvic floor physical therapy, even when there is no obvious injury.

About one-third of cases have no clear cause.⁴ It could be due to minor injuries that you don't remember. Or subtle problems in the way your body moves. Knowing what caused your pain helps guide the right treatment.

What are the symptoms of coccydynia?

The main symptom is pain localized at the tip of the coccyx. It intensifies when you sit down, when you move from sitting to standing, during bowel movements, or during sexual intercourse. The pain may spread to the buttocks or thighs. However, it does not follow specific nerve pathways like sciatica.

You can point to this pain with your finger. This specific location distinguishes coccydynia from sacral or lumbar problems. The pain can be sharp and stabbing when you change position. Or it can be a deep pain when you sit for a long time. People describe it as "sitting on a knife."⁸

• Pain directly at the tip of the coccyx (you can point to it with your finger)
• The pain worsens when you sit down, especially on hard surfaces.
• Shooting pain when you get up from a chair
• Pain during bowel movements
• Pain during sexual intercourse in certain positions⁸
• Leaning backward while sitting makes the pain worse.
• Leaning forward while seated helps⁹
• Sometimes the pain spreads to the buttocks or the back of the thighs.
• Anxiety about having to sit down
• Avoid social activities or work that require sitting
• Difficulty sleeping if you cannot find a comfortable position

Sitting is what makes coccydynia worse. The pain gets worse within a few minutes on hard surfaces. Cushions with cutouts help. They take pressure off the tailbone. Moving from sitting to standing causes sharp pain. This is because the tailbone moves and your weight shifts. Leaning backward while sitting worsens symptoms. It puts more pressure on the tailbone. Leaning forward helps. It shifts the weight to your thighs.⁹

Bowel movements can cause pain. This is because the rectum is close to the coccyx. The pelvic floor muscles also work during bowel movements. Certain positions during sexual intercourse worsen coccydynia. This is due to direct pressure or movement of the coccyx.⁸ The pain is usually localized. However, some people feel it spreading to the buttocks or the back of the thighs. This spread is different from sciatica. Sciatica follows nerve pathways and causes numbness or weakness.⁹

Long-lasting coccydynia creates other problems. You worry about sitting down. You avoid activities. You have trouble concentrating at work. You sleep poorly. If you recognize these symptoms, know that this is a common condition that responds well to treatment. These effects on daily life often prompt people to seek medical advice quickly.

How is coccydynia diagnosed?

The diagnosis involves a clinical examination with external and sometimes internal palpation. This reproduces the pain in the coccyx. The mobility of the coccyx is also assessed. Sometimes dynamic X-rays are taken. These compare the sitting and standing positions. In general, clinical observations are sufficient for diagnosis. Extensive imaging is not necessary.

The diagnosis begins with detailed questions. We want to know what your pain is like. What triggered it. What makes it worse or better. How it affects your daily life. We ask questions about spreading pain, numbness, and other symptoms. This helps rule out infections or tumors.¹⁰

The physical examination focuses on touching the coccyx directly. This recreates your pain. Pressing on the skin between your buttocks usually causes sensitivity. This is directly at the end of the coccyx. We check how the coccyx moves. We gently push on the bone. This shows whether it moves too much, not enough, or if it is in an abnormal position.¹⁰ Some practitioners perform an internal examination through the rectum. This allows them to feel the front of the coccyx directly.

Checking the tension of the pelvic floor muscles can reveal muscular problems. Trigger points in the levator muscles can send pain to the tailbone.⁷ Examining the mobility of your lumbar spine and the function of your sacroiliac joint eliminates pain coming from higher up. This assessment also rules out other conditions such aslumbar osteoarthritis or spinal stenosis, which can cause similar symptoms.

What tests confirm the diagnosis of coccydynia?

The diagnosis is based mainly on physical examination, not on tests. X-rays rarely change the treatment. However, they can show fractures or abnormal bone structure. Dynamic X-rays compare the position of the coccyx when standing versus sitting. They can show excessive movement. However, experts debate whether this is important.¹¹ MRI shows soft tissue. It does not add much information in typical cases. Imaging is necessary when the examination shows warning signs. For example, an infection, tumor, or serious trauma.¹⁰

When is imaging necessary for coccyx pain?

Imaging is necessary in certain cases. For example, severe constant pain that does not change with position. Symptoms such as fever or weight loss. A history of cancer. Worsening nerve problems. Or trauma that could have caused an unstable fracture.¹⁰ Rest assured: these situations are rare. For typical cases without warning signs, diagnosis based on pain patterns is sufficient. Sensitivity when touching the coccyx confirms the diagnosis. Treatment can begin. Findings on X-rays often do not correspond to symptoms. People without pain may have the same X-ray results.¹¹

How does physical therapy treat coccydynia?

Physical therapy combines several approaches. Manual therapy is used, including coccyx mobilization. Pelvic floor muscle training is performed. Posture is taught. Pain management strategies are used. The treatment addresses both the local dysfunction of the coccyx and contributing factors. For example, pelvic floor tension or postural habits. This is for complete relief.

Physical therapy is the first treatment to try. Research shows that it works in most cases.¹² Manual techniques target movement problems in the tailbone. Gentle pushes and movements are used. This can be done externally or internally. External work means applying gentle pressure through the tissue between your buttocks. Internal work is done by physical therapists who specialize in pelvic health. This allows direct movement of the tailbone. It restores normal function and reduces muscle tension.¹³

Pelvic floor muscle training treats muscle problems. This is especially important when tension in the levator muscles causes symptoms. Or when there are trigger points. For cases that require specialized pelvic floor attention, our perineal physical therapy program offers treatments tailored for men and women. Treatment includes releasing tight tissue, training coordination, and stretching tight muscles.⁷ Postural education teaches you how to change the way you sit. Leaning forward slightly shifts your weight from your tailbone to your thighs. Using lumbar support keeps your spine properly aligned. It also makes it easier to lean forward.¹⁴

Education about the science of pain helps you understand it better. It reduces anxiety, which can worsen pain. Exercises for core strength and hip flexibility support healing. They improve the way your body moves.¹² To better understand our comprehensive approach to treatment, learn everything you need to know about physical therapy and how it can effectively treat your condition. Our physical therapists at Physioactif perform a complete assessment. We customize treatment for your coccydynia.

What changes in sitting position help coccydynia?

Use tailbone cushions with cutouts. This takes pressure off the tailbone. Alternate between sitting and standing. Lean forward slightly when sitting. Avoid sitting for long periods on hard surfaces. Good ergonomic design and frequent changes in position greatly reduce pain. This helps with daily activities.

• Choose cushions with cutouts that relieve pressure on the tailbone.
• U-shaped or wedge-shaped designs work best¹⁵
• Look for medium-firm support (not too soft).
• Choose the right size for your chair
• Keep cushions at work, in your car, and at home.

• Lean forward slightly to shift your weight from your tailbone to your thighs.
• It can reduce pressure on the tailbone by up to 80%⁹
• Don't lean backward—it makes the pain worse.
• Keep your feet flat on the floor.
• Position your hips at knee level or slightly higher.

• Set an alarm every 20 to 30 minutes.
• Get up and move
• Change position regularly
• Use a standing desk if possible
• Alternate between sitting and standing throughout the day.

• Adjust the height of the chair so that your feet rest flat on the floor.
• Avoid soft chairs that make you lean backward.
• Add padding to hard surfaces
• Use a lumbar support to make it easier to bend forward.
• Ensure you can maintain good posture

Coccyx cushions are the fastest way to get relief. Keep one at work, in your car, and at home.¹⁵ Leaning forward shifts the weight from your coccyx to your thighs. This reduces pressure by up to 80%.⁹ Standing desk converters allow you to alternate between sitting and standing throughout the day.¹⁴

What is the recovery time for coccydynia?

Most cases of coccydynia improve within 8 to 12 weeks with appropriate treatment. Acute traumatic cases may resolve within 4 to 8 weeks. Chronic cases may take 3 to 6 months. Cases that persist beyond one year may require additional interventions beyond physical therapy.

Rest assured: most cases of coccydynia improve with the right treatment. Recovery time depends on what caused your pain, how long you have had it, and how well you follow the treatment. Recent coccydynia following trauma generally responds well. You will notice improvement within 2 to 4 weeks. Major relief occurs around 8 to 12 weeks.¹⁶ Starting treatment early speeds up recovery. It also prevents chronic pain.

Chronic cases take longer. They often require 3 to 6 months of regular treatment. Chronic pain involves changes in the brain. It takes time to reverse. Even after the tissues heal.¹⁶ Several things affect the speed of healing. Continuing activities that cause pain slows down recovery. Not following changes in sitting position does too. Anxiety and catastrophic thinking (thinking it's worse than it really is) slow everything down.¹⁴ Pelvic floor problems, tailbone fractures, and obesity make recovery more difficult. This is because they require more healing time. Or because they continue to put stress on the tailbone.¹⁷

Approximately 90% of cases improve with treatment within one year.¹⁶ The remaining 10% with pain lasting beyond 12 months despite complete treatment may require injection therapy. Surgery is rarely necessary. Expect symptoms to fluctuate during recovery. Overall, there is gradual improvement, even if there are occasional flare-ups.

What activities should be modified with coccydynia?

Temporarily avoid sitting for long periods of time, cycling, and rowing. Also avoid exercises that put pressure on the tailbone. Modify activities by using standing desks. Take frequent breaks. Choose appropriate seating. Avoid direct pressure on the tailbone until symptoms improve with treatment.

Changing activities is the basis of coccydynia management. It removes stress on the coccyx. Sitting for long periods of time requires strategies. For example, change position frequently. Use special cushions. Alternate postures. Start by limiting sitting to 20-30 minutes at a time. Increase slowly as symptoms improve.¹⁴

Cycling puts constant pressure on the tailbone. Repetitive movements worsen the symptoms. Stop cycling completely during the acute phase. This prevents flare-ups. Gradually return to cycling using wide, padded saddles. Only when the pain has improved significantly. Rowing creates similar stress due to the sustained sitting position and repetitive trunk movements.¹⁸

Change your exercises to take direct pressure off your tailbone. While staying fit. Floor exercises done lying on your back or stomach need extra padding. Or they should be avoided if touching your tailbone hurts. Replace seated exercises like stationary bikes. Use standing options or recumbent bikes. Swimming is an excellent low-impact exercise. It keeps you fit without putting strain on the tailbone.¹⁸

Return to activities based on your symptoms. You can resume an activity when doing it does not worsen the pain beyond your baseline level or when it does not cause flare-ups the next day. Start with short periods (5–10 minutes) and increase slowly based on your response. This allows you to return safely without setbacks.¹⁴

When are injections or surgery considered?

The good news is that more than 90% of coccydynia cases resolve without surgery. Injections are considered after 2 to 3 months of conservative treatment that has not worked. This is for temporary relief and to confirm the diagnosis. Coccygectomy (surgical removal) is rare. It is reserved for severe chronic cases. When all conservative measures have failed for 6 to 12 months. With significant disability.

Corticosteroid injections (a powerful anti-inflammatory medication) are the second option. They are used when physical therapy and lifestyle changes do not work after 8 to 12 weeks. The injections deliver the anti-inflammatory medication directly to the painful area. They can provide relief for several months.¹⁹ If the injection stops all pain, it confirms that the coccyx is the real source. This helps guide the next steps.¹⁹ The effectiveness of injections varies greatly. Some people get lasting relief. Others get temporary relief or no improvement.

Surgery (coccygectomy) involves removing part or all of the coccyx. It is a definitive treatment for cases that do not improve. However, it carries risks and results vary. Surgery is only considered after 6 to 12 months of comprehensive treatment that has not worked.²¹ Success rates range from 60 to 90%. It depends on who receives it. The best results occur in patients who have a clear traumatic cause and a mobile coccyx on examination.²¹

• Infection
• Wound healing problems
• Rectal injury
• Pain continues even after removal

Other treatments for persistent coccydynia include radiofrequency ablation. This is a technique that uses heat to deactivate the nerves that send pain signals. Prolotherapy (injections that stimulate tissue healing) is also used. The research supporting these treatments is limited.²⁰

How can coccydynia be prevented?

Prevention includes using appropriate protective equipment in sports. Maintain good sitting posture. Take regular breaks from prolonged sitting. Strengthen the core and pelvic floor muscles. Use an appropriate cushion on hard surfaces. This is to minimize stress on the tailbone.

• Wearing padded shorts in sports with a risk of falling
• Learn to fall on your side instead of on your bottom²²
• Choosing the right bike seat (wide and padded)
• Adjust the position of the bike correctly
• Increase training gradually¹⁸
• Using the correct rowing technique

• Use well-padded chairs
• Take movement breaks every 30 to 60 minutes.
• Maintain good sitting posture
• Use a coccyx cushion if needed
• Arrange the workspace ergonomically

• Strengthen your core muscles
• Strengthen your pelvic floor muscles⁷
• Maintain a healthy weight
• Avoid sitting on hard surfaces without padding.
• Change position regularly

Primary prevention focuses on avoiding direct trauma and repetitive stress. Athletes in sports where you might fall should use protective equipment. For example, padded shorts. These cushion the impact on the tailbone. Learning how to fall correctly helps. Rolling onto your side instead of landing on your buttocks reduces the risk of injury.²²

Proper workspace design can help prevent coccydynia. For jobs that require a lot of sitting, use chairs with good padding. Take breaks to move around every 30 to 60 minutes. Maintain good posture. This protects the coccyx from chronic stress.¹⁴ Strong core and pelvic floor muscles create better core stability. This reduces excessive strain on the tailbone. Strong core muscles keep your spine aligned. Forces are distributed evenly throughout the pelvis.⁷

Athletes in high-risk sports such as cycling and rowing should ensure that their equipment is properly adjusted and that their technique is correct. Choosing the right bike seat helps, as does adjusting your position. Gradually increasing your training prevents repetitive stress.¹⁸ Pregnant women are at higher risk during and after childbirth. Our program for pregnant and postpartum women includes pelvic floor physical therapy before birth. This can prepare the tissues for the stress of labor and may reduce the risk of coccyx injury.⁵

Secondary prevention is for people who have already had coccydynia. It focuses on preventing it from coming back. Continue to use good ergonomics. Continue core and pelvic floor exercises. Avoid direct trauma. Knowing your individual risk factors allows you to target prevention strategies.²²
