I did get some relief from the SNB injections all though it was short lived maybe lasted a week or a week and half at the most. As for the green light from my insurance I'm looking forward to the trial and first meeting this new doc. My wife on the other hand is scared that something is going to go wrong (because of the restrictions) but I told her I want this to work for US so I will do anything to get rid of some of this pain. She also is have problems at L4 & L5 right now .
