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

The tailbone can be found at the end of the spinal column. It supports the body in a sitting position and helps transfer body weight during changes in sitting positions. It is also an area where muscles, nerves, ligaments, and tendons from other locations in the body come together. Excess pressure can affect these structures.
In most cases, the specific cause of coccydynia is not known. Other times, it may be caused by: Trauma or injury from fallsTailbone shift during childbirthOther stress that affects that tailbone
Pain can come from bones, muscles, nerves, or supporting structures.
Coccydynia is more common in females. Other factors that may increase your chance of coccydynia include:
Brittle bones, which can occur with
Joint inflammation or changes in bone structure, which can occur with
arthritisParticipation in contact sports or certain activities, such as horseback riding
Dislocation from injury or
, which can cause bones to shift
Prolonged sitting on hard surfacesLow back pain
Infections, such as
osteomyelitisSpinal cyst or tumor
Pain may occur when: Sitting downChanging position from sitting to standingHaving a bowel movementHaving sex
Coccydynia may cause: Tenderness directly over tailboneAll-over backachePain or spasm of pelvic or rectal muscles
You will be asked about your symptoms and medical history. A physical exam will be done. This will include an evaluation of the tailbone to see if the area is swollen, red, or warm.
Imaging tests to look for fractures, dislocation, or other damage in the tailbone may include: CT scanX-ray
In most cases, coccydynia will resolve on its own with conservative treatment. This includes using a special seating cushion to relieve pressure on the tailbone.
If the coccyx is misaligned, it may be manually manipulated into place. Other treatments include:
Inflammation and/or pain may be relieved by: Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofenSteroid injectionsNerve blocksAntidepressants
Stool softeners can help reduce strain during bowel movements.
Physical therapy may include: Exercises to strengthen muscles and supporting structures, such as ligamentsRelief and stimulation with heat therapy and ultrasound therapy
Some people find relief with: MassageTranscutaneous electrical nerve stimulation (TENS)
Your doctor may also refer you to counseling.
Coccygectomy is the surgical removal of the tailbone. This surgery is not generally recommended and may be considered if all other treatment methods fail.
To help reduce your chance of coccydynia: Learn proper sitting postureIf you have to sit for long periods at work, get up and move around periodicallyUse proper protection during sports or activities where you may be injured
