Coccygodynia

Coccydynia is pain in the coccyx, the small bone at the bottom of your spine. This condition causes pain when you sit down and when you change position. It makes work, driving, and daily activities uncomfortable. Rest assured: coccydynia is easily treatable. More than 90% of cases improve with conservative treatment. Our physiotherapists specializing in pelvic health offer effective treatments that combine manual therapy, pelvic floor work, and lifestyle changes. Although coccydynia is specific to the tailbone, it is part of the range of back pain conditions we treat.

What is coccydynia and where does it hurt?

Coccydynia is pain in the coccyx, the small triangular bone at the very bottom of your spine. The pain is located exactly at the tip of the coccyx. You can point to it with a single finger.

The coccyx is located just below the sacrum. It is a bone formed of 3 to 5 fused vertebrae. The pelvic floor muscles attach to this bone, which explains the connection between the two. The coccyx supports about 2 to 10% of your body weight when you are sitting. That is why sitting makes the pain worse.

Women experience coccydynia about five times more often than men. Their pelvis is shaped differently, and childbirth can injure the coccyx. The female coccyx also moves more and is located further back, making it more vulnerable.

The pain of coccydynia is different from other types of back pain. Sacroiliac pain is located higher up and to the side. Lumbar problems are located above the sacrum. This distinction helps to make the correct diagnosis.

What causes tailbone pain?

Coccydynia often results from direct trauma, such as falling on the buttocks or injury during childbirth. Other causes include prolonged sitting on hard surfaces and repetitive sports such as cycling or rowing.

Pelvic floor problems are an often overlooked cause. The levator ani muscles attach to the coccyx. When these muscles are too tight or have trigger points, they cause pain that is felt in the coccyx. This explains why some cases improve with pelvic floor physical therapy, even without obvious injury.

Unlike lumbar sprains, which affect the ligaments in the lower back, coccydynia directly affects the coccyx bone.

What are the symptoms of coccydynia?

The main symptom is pain localized at the tip of the tailbone. It worsens when you sit down, when you get up from a chair, or during bowel movements. You can point to the pain with a single finger.

People often describe this pain as "sitting on a knife." The pain can be sharp when you change position, or deep when you sit for a long time.

• Pain directly at the tip of the coccyx
• Pain worsens on hard surfaces
• Severe pain when getting up from a chair
• Pain during bowel movements
• Occasional pain during sexual intercourse
• Leaning backward relieves the pain.
• Leaning forward helps

The pain may spread to the buttocks or the back of the thighs. However, it does not follow nerve pathways like sciatica. There is no numbness or weakness.

Long-lasting coccydynia creates other problems. You worry about sitting down. You avoid activities. You have trouble concentrating at work. If you recognize these symptoms, know that this is a common condition that responds well to treatment.

How is coccydynia diagnosed?

The diagnosis is based primarily on clinical examination. The coccyx is palpated to reproduce the pain and assess its mobility. Imaging is rarely necessary unless warning signs are present.

The physical examination focuses on touching the coccyx directly. Pressing on the skin between your buttocks causes sensitivity at the tip of the coccyx. We also check how the coccyx moves to see if there is too much or too little mobility.

Checking the tension of the pelvic floor muscles helps identify muscle problems. Trigger points in the levator muscles can send pain to the tailbone. This assessment helps rule out other conditions such aslumbar osteoarthritis.

When is imaging necessary?

Imaging becomes necessary in certain cases:

• Constant severe pain that does not change with position
• Fever or unexplained weight loss
• History of cancer
• Severe trauma with suspected fracture

Rest assured: these situations are rare. In typical cases, a diagnosis based on pain and sensitivity to touch is sufficient. Treatment can begin without imaging.

How does physical therapy treat coccydynia?

Physical therapy combines manual therapy of the coccyx, pelvic floor work, posture education, and pain management strategies. It is the first treatment to try. It works in most cases.

Manual techniques target problems with movement of the coccyx. Gentle thrusts and movements are used, either from the outside or the inside. Pelvic floor work treats muscle problems when tension in the levator muscles causes symptoms.

For cases requiring specialized attention, our perineal physical therapy program offers tailored treatments. To better understand our comprehensive approach, learn everything you need to know about physical therapy.

What changes in sitting position help coccydynia?

Use a tailbone cushion with a cutout. Lean forward slightly when sitting. Take breaks every 20-30 minutes. These changes can reduce pressure on the tailbone by up to 80%.

• Choose cushions with cutouts that relieve pressure.
• U-shaped or wedge-shaped shapes work best.
• Keep cushions at work, in the car, and at home.

• Lean forward slightly
• Do not lean backward
• Keep your feet flat on the floor.

• Get up every 20 to 30 minutes.
• Move around and change positions
• Use a standing desk if possible

• Adjust the height of the chair
• Avoid soft chairs that make you lean backward.
• Use lumbar support

What is the recovery time for coccydynia?

Most cases 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.

Several things affect the speed of healing. Continuing activities that cause pain slows down recovery. Anxiety and catastrophic thinking do too. Pelvic floor problems and obesity make recovery more difficult.

Rest assured: approximately 90% of cases improve with treatment within a year. Expect symptoms to fluctuate during recovery, with gradual improvement overall.

What activities should be modified with coccydynia?

Temporarily avoid prolonged sitting, cycling, and rowing. Modify floor exercises with padding. Gradually resume activities as symptoms improve.

Cycling puts constant pressure on the tailbone with repetitive movements. Rowing creates similar stress due to the sustained sitting position.

Swimming is an excellent alternative exercise. It keeps you fit without putting strain on your tailbone. Return to activities when doing them does not worsen the pain beyond your baseline level.

When are injections or surgery considered?

The good news: more than 90% of cases resolve without surgery. Injections are considered after 2 to 3 months of conservative treatment that has not worked. Surgery is rare and reserved for severe chronic cases.

Corticosteroid injections deliver the anti-inflammatory medication directly to the painful area. They can provide relief for several months. If the injection stops all pain, it confirms that the coccyx is the true source.

Surgery (coccygectomy) involves removing part or all of the coccyx. It is only considered after 6 to 12 months of comprehensive treatment that has not worked. Success rates range from 60 to 90%, with the best results in patients who have a clear traumatic cause.

Other treatments for persistent coccydynia include radiofrequency ablation and prolotherapy. Research supporting these treatments is still limited.

How can coccydynia be prevented?

Prevention includes using protective equipment in sports, maintaining good sitting posture, taking regular breaks, and strengthening the core and pelvic floor muscles.

• Wearing padded shorts in sports with a risk of falling
• Learn to fall on your side instead of on your bottom
• Choosing the right bike saddle and adjusting the position

• Use well-padded chairs
• Take movement breaks every 30 to 60 minutes.
• Maintain good sitting posture

• Strengthen your core and pelvic floor muscles
• Maintain a healthy weight
• Avoid sitting for long periods on hard surfaces without padding.

Pregnant women are at higher risk. Our program for pregnant and postpartum women includes pelvic floor physical therapy, which can reduce the risk of tailbone injury.
