I had a TENS unit for a damaged nerve in my ankle. The pain was so
bad I could hardly walk. The TENS unit took away the pain, and
helped the problem so much that I was pain free after using it 23 1/2
hours a day for five weeks. It has no side effects and is non-invasive. My biggest complaint was that my unit ate a battery every two days. I would definitely recommend giving this a try! Even if it does not help, it certainly won't hurt you or make the problem worse.
