Hello Im A 39 Year Female Who Has Had 2

Hello Im a 39 year female who has had 2 C-section on at 18years of age and another at 30 I was treated for PID when I was 17 at 28 I had a tubal pregnancy which I was taken to surgery for. I have been having a dual sharp pain on the right side of the pelvic, this pain comes a few days before my menstrual and will last a few days after my menstrual end or even sometimes the whole month. with this pain If I drink alcohol the pain comes. when Im sleeping and I wake up in the middle of the night the pain is there and relived when I empty my bladder. I have been with Kaiser who in 2008 I was givin a medication to send me into menapause to rule out endometriosis. I still had the pain without having a menstrual I was then taken to surgery and the physician said she seen a little scar tissue from the area of pain stretching back towards the anus which she removed and then she stated I have POCS. I would like to know if there is a specialist that your company may know that specialized in pelvic pain I don't think it is POCS and I believe it may be endometriosis.
