I had pelvic pain for 12 years that presented as a back injury. It came and went with ovulation every other month. At first, I went to OB/GYN, got abx every time. Then I tried physical therapy for back pain for 2 years. I did Lupron, and the pain went away for 2 years. Then same pain back for 8 years. I finally had a hysterectomy 16 months ago (still have ovaries). For the last 5 months, the same pain is back approx. every other month. Can t stand, walk, turn over in the bed without severe pain (8/10 pain). Aching and throbbing from naval to knees, and sharp pain in approx. L1-2 when try to stand or move. It lasts 2-9 days. Thank you!
