Dude...Iwas looking into a home ultrasound machine since I have a lot of scar tissue and adhesions in my muscles.
What brand did you buy?
Ultrasound is the shit for tendons and muscle injuries. I got mine at LGMedSupply. Its just the little handheld one. It was like $110. I tore my pec 10 years ago and have a ton of scar tissue that limited my movement and was constantly popping and causing a week or two lay off. Since starting it, I have a much better range of motion, I'm stronger, and no more strains. I also use it on other injuries and it speeds recovery amazingly. I always thought it was BS until I had my Dr. use it on a tricep injury. I ended up not even missing a workout.
