My tailbone hurts when i sit in certain positions, so much so that i often prefer to stand?

Coccydynia: Pain in the tailbone (coccyx) is most often caused by the simple act of sitting and, therefore, can be quite aggravating. Physical exam, dynamic sitting/standing xrs, mri/ct, and diagnostic injections can help confirm the diagnosis. A sitting cushion with a cutout ('doughnut') can help alleviate pressure while sitting. Surgery via excision (coccygectomy) is rarely ever indicated.

Coccydynia: There is a medical condition known as coccydynia that literally means- pain in the tailbone. It's cause is not known, but can make it painful to sit. Sometimes it will improve on it's own. If it does not improve and gets particularly severe we sometimes use an injection to treat it. Thank you for the question.
