I am using it for chemoneuropathy and muscle pain from Myasthenia Gravis. It must be working because when I feel better I forget to take it! The first time I used it I must have take too low a dose; because it didn't really work well for me. I heard about a neurologist using it in Florida to treat a lady with MG so I bought some in a higher dose. You can always add to your dose so I don't recommend beginning high; but low and work your way up.
