I haven't been exercising for a while, and three days ago I decided I'd go jogging outdoors. I am currently in Germany, and like most of the pavements in Germany, they are inclined towards the road to direct rain water.
I was jogging around a block in a counter-clockwise direction. After two days of running (45 minutes each I guess), I started to feel a pain in my left knee. I can tell that it is not just a muscle ache, and it is only in my left knee, which apparently was pressing against a higher ground of the pavement than my right one. It hurts when I extend my left leg while walking.
Should I worry about this? I thought next time I'd do it clockwise instead, is this a good idea?
