You might have the doctors check you for Thoracic Outlet Syndrome. I have this, and the symptoms you describe sound exactly like this. I have it on both sides, but had a rib removed to help on one side, and I still need to have it done on the other side. I also have carpal tunnel, and need surgery for that, too. I went to a Neurologist that diagnosed it, and then on to a Thoracic Surgeon. You might look up some info on the net and study up on the Thoracic Outlett Syndrome to see if your symptoms fit the illness. Good luck
