Hi there,
I had spasms in my entire left arm and shoulder. I found a doctor by the name of Emran Sheikh of the Rothman Institute in NJ/Philly. He did a Open Carpal Tunnel Release and a Ulnar Nerve Transposition. This surgery has helped my spasms a lot. He's a wonderful neuro doc and has wonder bedside manner. If you have any questions msg me or email me.
