I have a friend who has RSD. It is affecting his right arm and shoulder which is red, has a burning sensation and pain. All fingers except the index finger are numb. His right arm is now smaller from lack of use. He also gets headaches that start at the base of his neck and move up and over to his forehead. He was injured in a 7 ft fall from a step ladder and landed on that right arm. He is being treated by medical doctors but the drugs he's being given haven't really helped much. Can you give me a place to start with him? Which meridians and points would be best based on this information? Thank you for any information you can give me.
