Coccydynia is pain in the tailbone (coccyx). The coccyx is a small, curved, V-shaped bone at the bottom of the spine.

In some people the cause is not known. In others, it may be due to:
- Trauma, such as:
- A backwards fall onto the spine (most common)
- Problems during childbirth
- Epidural injection
- Rectal or spinal surgery
- Repetitive or prolonged sitting that causes trauma over time
- Bone spurs
- Changes in the normal structure of the coccyx bones
- Cancer (rare)
This problem is more common in women and young adults. Other things that may raise the risk are:
- Trauma, especially a backwards fall onto the back
- Rapid weight loss
- Surgery to fuse the sacrococcygeal joint
The main symptom is pain in the tailbone. It may happen when:
- Sitting down
- Changing position from sitting to standing
- Having a bowel movement
- Having sex
The doctor will ask about your symptoms and health history. You may also be asked about any recent injuries. A physical exam will be done. It will focus on the tailbone.
Images of the spine may be taken. This can be done with:
The goal of treatment is to manage symptoms and allow the area to heal. Rest from physical activities will be needed. Other choices are:
- Easing pressure on the tailbone with a cushion and cold or warm compresses
- Medicines, such as:
- Pain relievers
- Steroid injections
- Nerve blocks
- Physical therapy to improve strength, flexibility, and range of motion
- Radiofrequency ablation to disrupt pain signals using electrical energy and heat
People who are not helped by these methods may need surgery. Coccygectomy is the full or partial removal of the tailbone. This is rare.
There are no known guidelines to prevent this health problem.
