Ultrasound Therapy

I have had this done before. I have chronic neck and shoulder pain which causes serious  headaches.  I used to go to PT and they would do this at the end of the session. It's supposed to warm and loosen the muscles deeply. Deeper than what a massage would do. The first few times it felt good b/c they would go over tight spots and it felt like a pressure point being relaxed. after so long I became used to it and preferred a message. But I believe it helped with multiple sessions. Eventually I stopped going to PT. The chronic pain came back but I'm dealing with that on my own now. But it does work and is a pretty neat tool.
