I did the first two sessions of W9 last week and felt fine. On the next rest day I stood up from a chair (dangerous things) and tweaked my right knee. It was swollen and painful for a couple of days so no more running. I thought it was just one of those things, but then yesterday afternoon the other knee hurt in the same place and was also swollen. If you were looking at my kneecaps the swelling would be at 4 o'clock on the right knee and 8 o'clock on the left knee. I now realise that it must be a running injury. Any thoughts? I must rest for a few more days but presumably I'd better try a couple of lighter sessions before I attempt W9R3, or should I go back and do the last few weeks again. I feel very downhearted.
