I had surgery in my shoulder and they removed the bursa, took out scar tissue and repaired a tear. Now they think a pinched nerve in my neck. The pain has affected my whole arm. Now I have a rash on my hand for the last 2 months. It itches and pains. Then will peel. To start the cycle again. I use cortizone on it. It helps the pain and itching. What is the rash. It looks like a bad burn.
