Wow, I was just trying to make a joke about the laser pointer, I had no idea that could actually work. Maybe I should try it on my shin scrapes from deadlifting.
I was just extrapolating what I know about ultrasound, and I was taught that you can burn the bone if you stay in one place too long, so the wand must continually be moved. Vetrolasers sound very safe by comparison then if they cannot damage tissue.
I may seriously consider saving up for one now. I think my next major purchase will be compex electrostim machine, but I think the Vetrolaser just made my wish list. Although the female of house seems to think we need a new dishwasher....
