It may be Coccydynia
, Coccydynia is more common in women since the female pelvis is wider and the coccyx is therefore exposed. Very thin women are at even greater risk since the fat padding of the buttock is minimal and does not cushion the coccyx when sitting. These days coccydynia has become more common as the modern lifestyle has become largely sedentary and involves sitting for long periods of time.Tailbone pain
itself can be treated conservatively with a seat cushion, reducing the sitting time or at least sitting in an appropriate position that reduces weight on the coccyx. Physical therapy
will be a best measure. NSAIDs help to reduce the inflammation and control pain. In more severe cases corticosteroid and even anesthetic
injections may be necessary. Although extremely rare, surgical removal of the coccyx (coccygectomy) may be considered for patients with severe tailbone pain who do not find relief with other therapeutic measures.
