I have a severe pain on the right side of my neck. Starting from medulla oblongata it runs till my fingers in the ride hand. It is due to excessive usage of mouse and smart phone. I cannot reduce it because it is part of job which I do for my livelihood. This pain is in on and off for almost 7 to 8 years now. Other than that I don't have any other pain in my body although I am diabetic. The pain is not due to any external injury as well. It started occasionally but now it is unbearable at times. I am not sure if it is related to any mechanics involved in the neck shoulder and arms joint bones.
