@starbright375 A tens unit helps neuropathy in my foot. I had a knee replacement many years ago, and the doctor completely cut a nerve leading to my foot. I've had the needles feeling in my foot every since. After about 15 years, I thought of my tens unit and tried it. What a relief for about 4 nights. Now I use it about once a week. I've read if you have heart issues, you shouldn't use near your heart. I do have heart issues, but my foot is not near my heart, so I decided to use it. That info came from AI.
