Arm nerve pain post surgery

For a couple of weeks after surgery, the burning pain was so bad that I was convinced I was blistering and bleeding.  I couldn't believe that there was not even a sign of redness under my arm.  My GP gave me some soft wadding (the kind they put under casts, etc) which I taped in place so that it covered the entire area and stopped any skin to skin contact.  That helped a little.  Mostly, it's a matter of time.  Two and a half years later, the area is still numb and occasionally fires with random sensations but I'm more used to it.  Keep up your exercises.
