About 2 years ago I had laproscopic surgery to remove several cysts from my ovaries and endometriosis from behind my uterus. Recently I have been having pain in my left lower back and pelvic area. I had a ct scan and it came back that I have several cysts on my left ovary the biggest being 3 centimeters. My question is do you think I should have a hysterectomy how would they do it and what kind of cysts do you think they are? Im 26 and have 4 kids.

This is not a doctor online site. Anyone can answer.
No responder here, doctor or not, is going to tell you whether to have a hysterectomy, or guess at what kind of cysts you have. Those answers have to come from people who have a detailed knowledge of your current and past medical condition, not the few sentences you wrote here.
