I have always had painful periods and now having difficulty conceiving and was told I have endometriosis lately. For the past four cycles I have been severe pelvic/vaginal area pain mostly in the right side radiating down my legs and also pain in my left upper abdomen. I have needed to go to emegency department twice and needed iv hydromorohone. Surprisingly my periods are actually less painful now. I had a sonohysterogram four months ago; could that be causing these pains? My ultrasounds have shown a chocolate cyst on the left side and three fibroids. I am waiting for a pelvic MRI in February and my ovarian cancer marker is slightly high (apparently that can happen with endo and fibroids). I just cant stop thinking what if I have cancer? I am just so tired and depressed from being in pain all the time. Has anyone had a similar experience?
