hello I have a pain in my buttcrack, I went to the doctor and got it checked out she told me it wasn t a cyst she think I hit my butt onto something. and I know I didn t. She told me to take a hot bath 2-3 times a day and to take Tylenol every 6 hours. And if it still hurts come back to take an xray. the pain stiiilllll is here nothing is helping!!
Here you need to check whether the pain is from lower back to buttock or only in buttock.  Or close to hip.  Based on that do take x-ray and I believe physical therapy or physiotherapy to will be helpful for you so visit a Physiotherapist to.  And do ask them some exercise for buttocks apart from regular treatment they give.  Also, if done with spinal exercise great. Hope it was useful for you.  Take care
