a) compresses with fresh leaves and/or roots, wrapped in Saranwrap, then velcro bandage, then heat pad for a few hours. You can also purchase dried comfrey leaves and roots.
b) Dr Christopher's Tissue and Bone Ointment; check out the 400 customer reviews on Amazon here.
Comfrey is a magical plant. It's also called Knitbone. I used it years ago on cracked ribs and made me feel better instantly.
Another miracle: Mary's Transdermal patches -- cannabidol, CBD (the type marijuana that has healing properties, but does not get you stoned). They cost $20 each, but boy, have they worked for me. Left on for 12 hours. Took away pain. The next morning I forgot I'd had an injury. With about 5 days of these two remedies I've gone from maybe 50% to 80% of full recovery. http://www.marysmedicinals.com/
Calcium citrate and vitamin D3
My doc recommended.

I've sort of done a blitz with these treatments and it's wonderful to get my hand working again. I haven't actually gone to rehab yet, because there is so much I do naturally in my daily life with my hands that I'm not sure I need "exercises." Each day I do more.
