I just came from my first appt. with a pt. I've done lots of meds, injections, massage, and nothing was really helping. But this was great! First the wrapped me up in these heating pad things and left for 20 minutes! That alone i would have paid for! But then they brought in two ultra sound machines and worked on my most tender tender points. Which happen to be my lower back, hips and butt. One pt did one side and the other pt did the other. THey did this for about 15 to 20 mins. It's not warm to the touch, but it provides a deep heat through sound waves. I felt so good, I thought I would fall asleep this morning at work. But so far so good! Just wondered if anyone else has had this treatment before. And if not, maybe you should give it a try!
