@greenacres Glad I can help out. Norm Black in Illinois has his own Scrambler company, and does the treatments. He owns Spero Clinic in Illinois, and as far as I know, is the only Scrambler therapy in Illinois. Norm knows many people connected to Scrambler Therapy, and probably can answer your questions and give you guidance. People come from different states to get his treatments. He is a good, honest man, and would be a knowledgeable person for you to talk to. My first 10 treatments of Scrambler treatment helped for about 2 or 3 weeks, but the second group of 10 treatments did nothing. For the first ten treatments, my pain was less than it had been for easily one year. Good luck, Lori
