I have been practicing glidewalking for some time after learning it from he book. I like it and don't want to go back to my old ways. I have had pain in my right knee for several weeks now and suddenly it dawned on me that this probably has to do with my change in walking technique. The pain is in the back of the right knee and it is very tender there. I cannot squat without a lot of pain because it seems to be a bit swollen there. I wonder if my new way of walking puts more of a stretch in that area. In the past I have had a blocked SI joint on the left side. This probably influenced my movements when I was still walking with my hips leading. How should I proceed? Keep walking? Rest? Use a painkiller?
