Suggest Treatment For A Cyst Appearing In The Ovary

A cyst was found after I had a MRI for my back pain. I had an ultra sound which showed a cyst in my left ovary as well as multiple fibroids in my uterus. I am 51, and post menapausal. I have also never been pregnant, but did take fertility drugs years ago while trying to get pregnant. I do have swelling in my abdomen as well. The pain in my back is chronic!
