Acupuncture
Before, my brain was sending the wrong signals to my arm and hand. That sucked. Now, the main problem isn't brain signals but just muscle tightness. My rehab doctor suggested acupuncture to relieve it. There is a doctor at the rehab hospital who has also trained in acupuncture. I have gone once.
Needles poked. It didn't hurt. I waited for a half hour. They came out. I haven't noticed a big difference. We shall see.
