question: Hi I have had a bad shoulder for 3 too 4 weeks I first had a x-ray which came back ok. Then had a steroid injection which didn t help I know have nerve pain in my right arm only there when I rest or am active. When I cough the pain is even more intense I have pins and needles in my hand nearly all the time and get a bad burning feeling on my skin of bicep when I elevate my arm
