Any here? Anyone had experiences with them? Views...all that, please. I have never been to one, never felt comfortable.....and had bad experiences in my family. My dad was going to one for his back, was being treated, when all along it was a perforated ulcer, which ended up rupturing. He also had COPD, which lead to his death. My BIL was going to one, being treated for sciatica, when in fact he had, and died from ALS. Anyway, I would appreciated if anyone has thoughts or experiences.
