I went and saw my pain doc and medtronics rep this week. They reprogramed my stim and my pm doc said I need to repeat the nerve blocks in the base of my head and neck. He said due to my positioning of my head during last surgery is what is causing this. He wants me to go get fitted with a neck collar and wear every night to bed. I just don't see wasting my money on one because I just dont see myself wearing it. I don't think it would be comfortable or be able to sleep with it on. Does any of you sleep with one or have did it before? Just looking for another opinon.
