“After months of sciatica pain shooting down my leg, I can finally sleep through the night.
The heat and stretch combo feels like a miracle in my living room.”
“I’ve spent hundreds on PT and nothing worked this fast. Ten minutes on the NerviFlex every evening and my lower back feels loose for the first time in years.”
“I hesitated because of the price, but it’s easily the best purchase I’ve made for my back. The traction and warmth actually do what they promise.”
NerviFlex isn’t another back massager — it targets the root cause of sciatica and back pain.
• Releases pressure from compressed nerves with precise spinal traction.
• Melts tension using deep, soothing heat that improves circulation and flexibility.
• Restores mobility through rhythmic vibration that relaxes overworked muscles.
• Built for daily use, 10 minutes a day is helping you move freely, sleep better, and finally feel like yourself again.
Each session combines three clinically proven therapies:
Traction gently decompresses your spine to relieve nerve pressure.
Heat increases blood flow and calms inflammation.
Vibration relaxes muscles and resets tension patterns built up from sitting or stress.
Together, they help your body realign, recover, and heal naturally — in just 10 minutes a day.
