I am looking into Scrambler therapy. It is only offered limited locations. The closest to me is at Johns-Hopkins in Baltimore. Just over two hours. If approved, it would require 10 sessions over two weeks. It's not covered by insurance. If, after the first week , you do not experience any relief, the treatment is stopped, and you are charged for that week only. Obviously, there are logistical problems. But, if it were to provide some relief, I would jump at the chance.
