Sciatic nerve issues are a special kind of hell. That stingy, nervy, intense pain down into the thigh, back of knee, heel or even foot happens on a spectrum. Some of us get occasional jolts, others full on numbness of the foot. It’s always best to get checked out by your doctor if you are experiencing these symptoms. But if you are in a management and healing phase, this practice can restore the sliding and gliding to your sciatic nerve both in the gluteal muscles and at the various nerve roots. This kind of suppleness is a big part of healing.
