I've always had painful periods and lower back pain, I've been told I have 2 endrometrius cysts on my right ovary and can have it removed. I tried natural cures, but it's getting worse...I don't want surgery. Is there anyway to shrink them? Could it be something else causing THIS MUCH pain? (10 out of 10) for 2 "little" cysts. Are there tests I should ask for? I'm also scheduled for a colonoscopy and upper GI in 1 1/2 months... I'm 44 and otherwise in good health. What about having them drained??? I can't function in this much pain and uncertainty.
