Recommend Increasing Power Gradually on OTC "TENS" Devices
You'll see more OTC "TENS" devices for pain...Icy Hot SmartRelief, Omron Electrotherapy Pain Relief, AccuRelief TENS Pain Relief System, etc.
These transcutaneous electrical nerve stimulation (TENS) units are promoted for back pain, muscle pain, joint pain, and more.
OTC units are comparable to the ones sold by Rx. FDA now allows them to be sold without an Rx based on long-term evidence of safety.
