im having cronic pain in my arms all the way down to my hands and fingers where at times it hurts to touch them

.some one told me the "EMG"test are painfull

its a test they have to do to my neck.they saw from my "MRI"and found there is a lot of damage there.had surgery and therapy to my shoulder but after 2yrs still no relief nor can i return to work.so they think its my neck with its rupter disc's.maybe pinching a nerve.anyone ever had this done

....thanks
