^^^^ this.
I was slowly increasing my kilometers run weekly. Last time I ran almost 10k, finished OK (could've run more but decided not to), but after that the pain on my knee was unbearable. Went to the physio (again), turns out the muscles in my left leg are very weak, causing pain in my left knee. Glutes are mainly the culprit.
I've been reading a lot about it, and it's all linked to ITBS. Now I got a foam roller to stretch (very painful), doing lots of exercises at home (clamshells, etc) to strengthen my butt.
Pinkboy, have you had ITBS before?
