Quell is a more advanced way to treat chronic pain. Like TENS units, Quell uses electrical nerve stimulation in order to provide pain relief., TENS devices range from very low dose devices available over-the-counter, to higher powered technology used in a healthcare setting. Quell 2.0 is up to 10x more powerful than typical over-the-counter (OTC) TENS devices*. Quell is powerful enough to stimulate the sensory nerves in the upper calf, which carry neural pulses to the brain triggering a natural response that blocks pain signals in the brain. Nerve stimulation, such as Quell, can have widespread effects that provide pain relief beyond the site of stimulation. Quell is also the only OTC electrical nerve stimulation device that is FDA cleared for use while sleeping and can be used during the day when active or at night when sleeping.
