I have a 30-year history of painful "knots" in my neck, shoulders and shoulder blades. I finally could take it not longer, so I ordered this unit. I applied the electrodes to the worst spots on the back. Then I ran a random set of programs, over and over again, for anywhere from 30 minutes... up to 5 hours per day. At first little seemed to be happening. Then I began to notice that my muscles were changing. They seemed to be "forgetting" their old habits, and felt different. I continued with the stimulator device, always mixing up the various programs that I used, and hitting my muscles with a variety of intensities, etc. After about one month of consistent use, I realized, one day, that I hadn't used the device in three days, and that I had no knots in my neck or back! It was absolutely amazing! This has continued now, for about three months. Now I just use this device periodically, when I feel that maybe my muscles are going back to their old ways, and I want to nip the problem in the bud, as they say! I recommend this product to anyone who has a chronic problem with knots in the muscles. Remember to stick it out and use the device every day until you have success. It may take a while, but it is well worth it!!
