B.H.
My husband had this done (he has three fractured discs). He had 14 shots done. He was awake. He said it was "uncomfortable" but he has been through worse. He got temporary relief, maybe 4-6 months.
He said that he would not do it again though. For my husband's issues, surgery is really the only option - and he really doesn't want to do that. So for now he just lives with the pain.
