There could be an infection under my knee-cap, don't know the exact word for it but it's the same soft tissue that's also in your ear, in Dutch it's called Kraakbeen. And it could be either irritated or infected. That's what the Docter said

So i have to rest it but also keep stretching it. I'm really confused as you can see
Might happend when i went Go-Karting, my foot was literlly glued to the pedal,but it could also been the jogging, playing Football or workout. No idea tbh but it hurts like hell when i stand up and start walking, plenty of rest should do the trick hopefully
