i understand your suffering...usually ovaries are retained as they are helpul for the body during tah..but unfortunately sometimes cysts are formed like in your case.......so now your prob.is back ache and abdominal pain
low back and pelvic pain
can sometimes be due to chronic pelvic inflammatory disease(mild infection in pelvis),adhesions due to operation,or swelling of tubes ovarian cysts.or laxity of pelvic muscles and ligaments.or harmonal ..
i suggest you to consult a gynaecologist or laparoscopic surgeon to do a diagnostic laparoscopy
to look in your abdomen and pelvis whats the problem is,remove tubes and ovaries if necessary,remove adhesions if any,under antibiotic cover..do regular exercise ,maintain ideal wt,take calcium,milk products
get well soon..take care
