I have nerve damage in my upper right arm from a gunshot wound, I was doing ok with range of motion and strength until I started using Nortriptyline, I was on it for 2 weeks, 2- 25mg daily. at the same time I started with 5lb dumbbell weight training coupled with 2-3 mile light runs. My strength & range of motion has decreased by 50%. Any suggestions/Info out there ???
