I also have the same issues had a TRH done three years ago this past April, Have inner groin pain, lateral hip & groin area extremely sensitive to touch have had four MRIs several x-rays doctor say no spinal stenosis, but have not ordered any new treatment to check for anything else. since my hip replacement I lean forward And cannot walk without a cane or something to hold onto and it has become worse over the last three years this week I was told it’s likely my right SI joint so they want to give me another injection through outpatient surgery said if I get even a little bit of relief, they want to fuse my right SI joint. I am concerned about having this done because what if it is not my SI joint I even asked my pain doctor for a CAT scan, ultrasound but he does not agree. Would be thankful to hear from any of you that have had your SI joint fused if it helped since my condition has worsened since my total hip replacement I keep thinking it’s related to that surgery and I could be wrong. Any advice any help would be more than appreciated.
