Good Advice from ipurr2. Make sure you get and keep all records regarding surgery, scans etc as some doctors miss vital information. It is possible the surgeon who did your surgery didn't remove it all so keep that in mind.
What you need to do is see an endometriosis specialist to get proper treatment for this disease! I did unfortunately lose my chance of having children because I did not get into the hands of an endometriosis specialist who does actual excision surgery (cuts it out) that is your best bet at beating this disease and keeping your organs...if you share with me city/state you live in I will try to put you on the best path with endo excision experts closest to you...most of us do have to travel...even after my hysterectomy with ovaries removed my endo continued to grow...so don't allow the dr. to talk you into taking those horrible drugs or having a hysterectomy because the only chance at a cure is to have the actual disease cut out by a specialist!
