The treatments are given in a series. How many are needed to truth a particular thing depends on what is being treated. It only Mt feet needed to be treated maybe 2 to 4 sessions would be needed. Because my neuropathy goes all the way to my knees on both legs, 8 sessions, 2 treatments in each session (for both legs) is 8 treatments. My cousin was treated for knees that were deemed untreatable except by knee replacement. He had 8 sessions testing both knees and has gone 8 weeks without the return of symptoms. Will I have the same success? Don't know. I don't know anyone else with neuropathy as advanced as mine who has done this kind of therapy. I hope I can deliver good news to anyone suffering sleepless nights from neuropathy pain.
