I have a pain right above buttocks crack for a few days now. And today while I was driving I cough nothing special just a simple cough, now it's really bothering me real bad. I can sit for too long before I get sharp pain, bending, squatting, laying down any physical movement is hurts. I have a high pain tolerance but its really getting to me now. I haven't had any injury that could remember and theirs no bruising or lump that you can see or feel. I can feel a sharp pain when i sneeze
