I was DG with Parkinson’s a year ago with a slight hand tremor. I have not started any meds yet, but I have started CBD/THC oil. I have found it has help me a lot with stiffness, sleep, it has helped my tremor, but still have them in evening when I get tired. I did consult with my movement specialist at Mayo before I started the oil, and he said still a lot of research needed but he had patients that like it....just don’t abuse. I also do the Big hand exercises daily and muscular message once a month. I am 75 years old and trying to stay off Parkinson meds as long as I can. It has really helped with my stiffness not sure how much is age related.
