Hi. I've been getting injections for over ten years and they really didn't help. All this time I was told and thought I had lumbar spine problems and other SI issues but this year my pain doctor hit the spot. It is piriformis syndrome. The medicare approved solution is very painful surgery to cut the muscle. The actual best method as I understand it is a simple botox injection. I am changing to a doctor that has lapriscopy in his office because the surgery center and hospital won't allow the injection and I don't want my pain doc shooting blind. Will post with results in a couple weeks. I haven't been able to sit, walk, stand, or even lay comfortably for a very long time. I've missed funerals, weddings, church, and countless other things. I hope and pray this is the cure!
