Jannelle,
I have a terrible time with my arms falling asleep at night. It will wake me up as often as the pain alone will. I dont know what to tell you to help with it just know you are not alone with it. For hypersensitivity mine is mostly on the top & I use a cream my pharmacist came up with for me. It doesnt work as deep as it sounds like you need. I put its name in another post. It works so well for that & the burning. I did find if I sleep with my worst arm on an extra pillow in bed it helps but only until I roll over & change positions. I am not good about staying in one position all night. Take care.
Hugs, Denny
