I've managed a couple of 5 mile runs and a bit of a footy kickabout in the past week, but my knee's giving me some proper jip. It hurts when I walk, kneel, especially when I run, and especially after running. Headed out yesterday but I had to walk back home after about half a mile. Not cool.
My attempts at self-diagnosis were inconclusive: I found 10 different knee injuries on one running website, with solutions ranging from 'Jog it off' to 'Painful Surgery'. I'm pretty fed up with it to be honest. So I'm going to go see the Doctor later today. We'll see what he says.
