I have been experiencing pain on lower left abdomen pelvic pain and nausea.Also lower back pain. I saw my colostomy Dr as I thought it was connected to that.I am postmenopausal and have been taking premarin for over 10 years. I had a hysterectomy at age 25 (I am now 57)they only left my ovaries. I had a cat scan and it shows some type of dense mass and they looked up a cat scan from a year ago and it was there then but smaller. It has been years since I have had an internal. I was told the ovaries were not there any longer, so not necessary to look for them. I am confused and I am worried. Can you shed some light on this please?
