Suggest Remedy For Pelvic Pain

Hello...
I am 25 years old, and looking for answers. Im starting to get very frustrated and very confused. I started experiencing pelvic pain last April (2009).. I went to the Gyne, where I was diagnosed with Endometriosis. I got the Lupron injection, however the pain was still there. Actually got worse. Finally a couple months later, I had exploratory surgery through the belly button. I found out at this point, I did not have the condition. I quit the Lupron. However over the next several months, the pain is a lot worse. I've been to the er several times, ct scans were performed. And nothing. I have been to the encrinologist.. where blood work was done, and was told I have PCOS. The pain, still hasnt gone away.. or eased. I was put on Metformin which didnt seem to make a difference, just make me extremely sick. I was then referred to Rheumologist. More blood work. My ESR rate was 63 in Nov. 75 in Feb, and now as of 2 weeks ago in March it is 83. Ive gained about 55 pounds since September, and recently gained 10 pounds alone in one week. I can't seem to get any answers, and the pain is worsening. Please help.
