I like my TENS but it depends on the day...sometimes I can't handle having anything on my skin. I did find it helps for sleep, I programmed mine for sleep. Hope it works for you...try messing around with the frequency until you find a good one. Also I suggest finding where the nerves are that you need to target and placing the TENS unit over that site. My pt just sent me home with it and said to put it where ever it felt good. My pain doc said to place it over certain nerves to get relief. Hope you get some relief.
