So I've decided to pick my lazy butt off the couch and start making some lifestyle changes, starting with a healthy diet and exercise. As you guys probably know, I have 2 herniations in my lower back, but the doctors have mixed opinions on whether or not it could be causing pain in my feet, so I have decided to hold off on surgery.... anyways, when I stretch, especially during the touching toes or the straight leg raise stretch, my feet start to tingle and eventually go a little numb. My legs are fine, just my feet tingle/go slightly numb. It gets better when I release the stretch. Any ideas on what this could mean? Thanks.
