I went to the er due to me having lower back pain and lower abdomen. They did a a swab and told me I may have a std then turned around and said no you have P I D. They took ult sound and ct and also said that I had a collapse cyst on my right ovary. I was treated with a shot. And was given a few pills. I am only sexually active with my husband and i am baffled on how I got it. How long could I have had this. Thank you for your time.
