Hi my burning started out on my face and then after my pump was replaced the pump and the tubing in the back shortly after that I started getting burning all on my upper body the back of my arms were the worst but it's horrible it's right when I sit down and laid back it gets after about 15 minutes it's really really bad I had to go to the hospital when I stayed in 4 days and they couldn't figure out what was wrong. I'm kind of thinking it might be where the tubing is in my spine could be pressing on a nerve I'm sure the doctors will say oh no that can't be it
