McKenzie self-treatments for sciatica

摘要

One of the most painful and disabling back problems is sciatica. This is a pinched nerve in your lower back that causes buttock, thigh, lower leg and even foot numbness, pain, and sometimes even weakness. Usually, the leg pain is worse than the back pain. Your spine may feel locked so you cannot straighten up fully and simple activities like bending, getting up from a chair or out of bed, or even walking can be impaired.
