The PainFree system simply returns lost space to the body. Every human body, including the body's connective tissue system, endures a normal amount of daily wear and tear.

Usually, a good night's sleep and sufficiently healthy lifestyle help the connective tissue return to normal the next day. But when connective tissue can't bounce back on a one-day turnaround, it continues to shorten and thicken, not just at the place it is overworked or stressed, but everywhere.
