I have had PN for over a year now and find it very debilitating. I have pins and needles in my legs and arms most days and am taking Gabapentin and a morphine patch 20 mg which I change weekly, all for the pain. It all does work to some degree but when I stress he pain increases especially early hours of the morning. I have also noticed the muscles of my arms and legs are shrinking. I am trying to find out if I do any walking of some distance I suffer that night and just cannot sleep. So does walking create more pain?
