Hi, the tail bone is called coccyx and pain in the tail bone is called coccydynia. It usually presents as pain only on sitting or reclining on a chair. Inflammation around the bone is usually the cause, but it can also be caused by fractures or dislocation/ subluxation. Other causes of pain around that region are perianal abscess and fissure.
