Hi Roni, the word 'hyperthermic' just means hot. Basically they're talking about heating up the tissue (Burning, I guess, when applied to a very small area of the body). I haven't heard anything about this treatment, or NIIM, but do check their results and the side effects carefully. Also carefully check their full list of charges- make sure you're not being charged a lot of money for something that is not particularly effective. I hope you find some good news. love Emily
