I think your treatment team would know what's your best option. I would give the acupuncture a shot though -find a reputable one - it can help. I have this portable battery operated device I bought years ago - looks like a pen on the end. My physio therapist recommended it at the time, because I had painful TMJ. When I would get spasms, I'd use it and it worked - it's also good for headaches. I think you should try standard(needles) acupuncture.

There are also pain clinics that teach people how to deal with pain. What's causing your pain Paddy? I wish I could take it away for you friend.
