How HFX works

Find Out How HFX Relieves Chronic Pain

How does HFX relieve pain?

The nerve pain you feel is caused by damaged nerves overproducing and sending abnormal pain signals to your brain.

HFX is a small device that safely delivers pain relief by sending gentle pulses to block those pain signals before you feel them, letting you get back to everyday life and the activities you love.
