The 28-Day NerveFix Challenge is a four-week, at-home program for numbness, tingling, and burning from the neck to the fingertips. You start with five short tests on Day 0 to find your two spots. Then you press play on twelve follow-along treatments, three a week, about 35 minutes each, in the same order every time: release the tight muscles pressing on the nerve, stretch what is now safe to stretch, and strengthen the muscles that keep the space open. Short Morning and Night Rituals cover the days between. On Day 28 you run the same five tests and compare the numbers. When you finish, the full NerveFix Blueprint unlocks, so the next time it flares you find it and fix it yourself. Everything runs in the NerveFix app: today’s treatment, timers on screen, your test sheet, and a checkbox for each session. Lifetime access. Finish-It Guarantee: complete all twelve treatments and both tests, and if your Day 28 numbers are not better than Day 0, email both sheets within 30 days for a refund.
