Suggest Treatment For Carpel Tunnel Syndrome

I have been diagnosed with carpel tunnel syndrome, but I have severe pain in my upper and lower arm muscles, worse at night, which has been ongoing for four years. Rest does not help, I cant wait for the sun to come up. It started in one shoulder, for about a year, then went to the other shoulder, and to both arms. My neck is very painful as well, it's driving me mad. Can you help.
