I experienced a neck/upper back injury during exercise about 10 years ago. This caused numbness, tingling, and weakness in my arms and hands and very much interfered with my quality of life and my sleeping. InterX is the only treatment that has helped me get relief from this long term problem. In addition, I believe it has helped me with other chronic issues such as sinus, migraines, and acute injuries. I also purchased an InterX home unit which I use between sessions to self treat. Having this has been a great help and enhancement to my getting better.
