Does CBD really work, what if you are on a bunch of other meds. I usually go in and get a steroid shot in my spine for pain but since I am also diabetic that shoots my numbers up and actually the shot isn't doing all that much. I have just heard about rhizotomy burn . Has anyone had that done, is it helpful and beneficial to have it done...…. About the CBD how do you know how much to take or does your dr. help with that...…. thanks,
