During Lidingöloppet I got the "Iliotibial band friction syndrome" (also kalled löparknä in Swedish). It hurts like hell at the side of the left knee and after I while and I have to stop doing any kind of activitiy and just sit down. It sucks. I thought I was in control of my body but the effort made for the race has given me some consequences. I got a time at the physiotherapist, he should help me to recover in a few weeks.
