I am a 48 yr old female of 5'7inches and 11.7 stone in weight. I have had previous problems with my right arm with pain radiating from my shoulder all the way down my arm over 2 years ago and received physiotheraphy and traction treatment at my local hospital. I was never told if this was a trapped nerve but assumed so.The problem cleared in about 2 months. Unfortunately this has come back again, and its a constant dull ache, which feels worse in the cold. Can you give me some advice and what I can do for my problem.
