How Does Quell Relieve Pain?

Quell uses transcutaneous electrical nerve stimulation (TENS) to stimulate sensory nerves in your leg with safe, painless, and precise electrical impulses to trigger a natural pain relief response. TENS devices like Quell have been used by physicians, physical therapists, and other health care professions for decades to manage pain.
