I had the same problem in 2005. It was so bad that I was losing muscle in my forearm and tricep. I was in the Military at the time and they sent me to a specialist. She recommended moving the nerve from its normal channel to the inside of my elbow away from the bone (I now have no funny bone on my left arm.) One surgery, a nasty scar and a some good painkillers later the issue is much better. It's still sensitive, but the numbness is gone. If the Military can find someone to help, anyone can.
