is this real? 6'7" 152 lb skinny 19 years old. Horrible food intake, although I drink lots of (if not only) water. Coffee in the morning of course. I have a professional job that has me behind a desk 10 hours a day for 5 days a week. It all started then, so maybe its related. What I have is throbbing (pulsating) pain in my lower shoulder/upper arm. It makes me cringe for a few seconds then fades away for 10 seconds before coming back. This will only happen once a day, but when it does happen it repeats this pattern for hours on end.
