Hi. I am sorry about your wife. I can relate as the blocks made me worse and the lidocaine infusion did as well. I am back on meds ones like neurontin and anti inflammatory and am trying to do other things like diet/supplement and possible hbot. Have you thought about possible hbot? I know most insurance does not cover for rsd so don't know if it would be an option. I know for me this could not be but have heard some here say it helps as the tens unit?Is there any of the meds like neurontin she has not tried that maybe she could try?I know when I called the treatment center the lady was nice and answered my ?'s but I did feel that it was the ketamine as there major focus and possibly the blocks and I am not sure though they said yes but I got a weird feeling about meds. I am sorry as I wish I had more answers or thoughts for you and your wife. I am here if you want to PM me anytime or your wife.
