Pain was located primarily in my rotator cuff, which led to muscle tension across my back and up into my neck. It would affect me in my work a day, my ability to relax and more importantly, my ability to sleep through the night. Since I started using DR-HO'S, I'm finding myself able to get through the work day, much, much better range of motion, no pain and most importantly, a great night's sleep. What I love about DR-HO'S is the variety of the treatment that is going through. You get power. You get the intensity in a very small, easy-to-use unit and the best part about it is, I don't have to make an appointment with anybody to get the kind of relief I get with the DR-HO'S product.
