Try using a Pulsed Electro Magnetic Field device, or PEMF for short. They have been effective in treating parkinsons disease. The devices themselves are not cheap, you if can find a provider who treat patients with one, then that is cheap. I myself suffered Parkinsons symptons as a young man, but was able to overcome it with PEMF treatment from a Delta Pulse machine. here is a link to such a story: https://www.youtube.com/watch?v=DNqExvp-yLA
