I've been feeling nerve pain in my left arm up thru the left side of my neck, passed my ear and into my head, I feel the left side "throbbing" and some numbness. I feel the same things on my right side as well, but not as much. I was in a drunk driving accident at 3 yrs. of age and had my head smashed into on the left side and sustained a brain injury, could it be possible that I would have problems with that now? My injury was in 1971. I have a newer injuries called Thoracic Kyphosis Acquired, sprained knee, pinched nerves, and I think TMJ [if that's an injury].
