Nancy Lee.I know nothing about your condition. However, I have used MJ for my parkinsons for years for pain and nausea that the "Meds cause and they provide a gentle euforia and sense of peace for me. Not with standing, MJ is not a cure for parkinsons, but a help!
That said, if it is legal where you live, as I did in California, get a little, get a friend to stay with you in case of any "paranoia" relax and smoke, don't eat it [it's tricky to gauge amounts with food] and relax like millions of people do all the time for relief of pain! I hope I don't get in hot water, but facts are facts, MJ is no more harmful for an adult with congenitive pain than any other pharmicutical drug! Good luck!
