I have had a history of past cysts on my ovaries. Starting 8 weeks ago I have been having pain on my lower left side, including lower back and top of leg. Sometimes just achy other times stabbing. I went to the OB 3 weeks ago and had a pelvic and ultrasound done. No sign of infection and Mirena in place. During the ultrasound he did notice that the left ovary was large and filled with many cysts. He decided to put me on a low dose birth control and to watch my symptoms. During the last 3 weeks the pain has not improved and I have had some spotting, which in 8 years of having a Mirena I never have. So he decided to run me through a round of antibiotics. So that is where I am now, halfway through and no relief. Trying to decide if I should get a second opinion or just give it time.
