Just a note on the low level laser treatment. I had lower back surgery in early 2008, and have been sore there and around my hips since the surgery. In the meantime, I’ve seen chiropractors, acupuncturists, massage therapists and physicians, and received temporary relief, usually no more than one or two days, but more likely in single digit hours. Given that, I’m skeptical about therapies, and experience little or no placebo effect. The laser therapy was different, especially after its application to the lymph gland in my shoulder. I felt relief, and it lasted for days after the first session, and a whole week after the third session. Thanks, and I appreciate your work and a sore-free low back.                                                                                                 Carr, Timothy B., Medical Librarian, Dallas VA
