HiDow wireless PAINLESS TENS is a single-channel transcutaneous electrical nerve stimulator (TENS) for over-the-counter (No prescription is required) use of pain relief. The device generates small pulses of electrical current and delivers the pulses to the user’s skin through adhesive gel electrode pads such that the underlying nerves are activated and the pain associated with sore and aching muscles is relieved. The PAINLESS TENS is portable, compact, rechargeable and stylish in design. It may help relieve pain in various areas of body, such as the lower back, shoulders, arms and legs.
