If I crouch or try to kneel and rest my bum on my legs, it feels as though I’m bending my knee so tightly that my thigh is going lower than my calf and whatever is inside my knee is going to snap. My thigh is nowhere near my calf but the pain is quite bad. Does anybody else get this as a symptom of runners knee? I’ve just spoken to physio on the phone who has said it sounds as though I have runners knee and told me to google it for some more info along with giving me some exercises, but I can’t see that symptom mentioned anywhere. I have cracking, crunching sensations and pain under my kneecap if I walk for longer than a few minutes or try to exercise, which do seem to be classic symptoms. The phone call was a bit awkward and I’m not sure I explained myself very well.
