My son, age 37, has severe back, neck, and head pain. He has had numerous tests, the shots, etc. There is a lot of muscle loss in his left arm. The EMG test indicates it is not a nerve problem. One Dr said c1,2 are problematic, as well as c5,6,7. The neurologist visit yesterday was of no help. He said, his best suggestion is to try the shots again.. I think he needs to see a second neurologist. Any other suggestions would be appreciated.
