If you're talking about me but this is not stem cell therapy this is a type of therapy where they put vitamins and minerals between plus we are case of hands and feet then suction cups all the places that mostly hurt which provide a type of vibration and electrical current to wake up the nerves. The treatment has worked out great for me. Before that I really couldn't even walk. I would have pins and needles Sharp and burning pains through my hands and feet all the time. So yes this treatment is worth the time and not stem cell.
