I Have Had Uterine Biopsy Ten Yrs Ago For Very

I have had uterine biopsy ten yrs ago for very minor bleeding. Very painful. Got an infection, hospitalized 3days. I have been in pain in pelvic region and lower back Ever since. Told I have scared tissue in that area. Have had many treatment and tests. I tried pelvic physical therapy. Some relief still in pain. I take vicodin. So tired of this. Ruined my life. Any ideas? ?
