I do not yet have a spinal cord stimulator placed. It was scheduled for the trial in April but I got a UTI so the placement was postponed. Now, I'm finding I need a new R hip. While I wait for the surgeon to have an opening, I got a steroid shot to relieve the pain from the disintegrating hip/hip socket. Surprise! My pain coming purportedly from L5-S1 and from the R S-I apparently was coming primarily from the R hip joint. I had a SPECT scan which showed rapidly proliferating arthritis at both L5-S1 and at the R S-I, but steroid injections had ceased to help at both of those locations. I was in considerable pain. And it turns out it was not from my spine or S-I joints, but from the R hip. I'm glad it has been located and with such a significant reduction in pain. All this is meant to say is to be sure that you and your neurologist are very certain your pain is coming from your spine before you have the stimulator implanted. I'm very glad to get so much pain relief from treating the deteriorating hip. It wasn't my spine after all.
