I had some hand problems earlier in the summer. It was mainly with numbness and shaking after I rode. The shaking usually went away pretty quickly but the numbness stayed around for about six weeks. I started to get relief when I used a massage/vibrator on my hand and the area between my shoulder blade and my spine. I evidently had caused a muscle to cramp in that area between my spine and shoulder blade. I could really feel it when I put the massager on it. It took about two weeks but I finally started to have some relief. I also kept riding during this time. I'm pretty stubborn. I think the nerve to that part of your hand comes out of your spine in that area. It worked for me. Hope you get some relief.
