for 3 years ive had pelvic pain. ive been to a gyn. and had a full hysterectomy (Im 32) just to find out that thats not the problem (great)

now my lower back the tail bone area is hurting bad and causing the same pelvic pain just much worst ive been to the doc and he seems to think ive injured my back and its a nerve thing.I have had no injury!!! He wants to send me to another gyno but ive already been to 2 of them and they send me back to my doc.its only been recently that the back pain has gotten worst ***** radiates to my groin and down my legs today it doesent hurt at all yesterday i could not walk sit or lay down

any sugestions would be highly appriciated. thx
