I was warming up yesterday on a roof with a decent heel-toe for your right. I did the move which I thought would have put the most strain on my knee but whilst trying to remember the beta for the next move with the heel-toe still in, something popped down the outside of my left knee. I walked it off for about five minutes then tentatively tried the climb again. No problems getting into the move but as soon as I put my heel-toe in and started to weight it it hurt. Has anyone else had a similar experience? Any recovery advice? I don't think it's too bad but I'm a bit worried and gutted as I'm off to Chironico in three weeks. Thankfully, there don't seem to be many heel-toe dependent problems in Chironico! Ta for any advice.
