stiffness tightness and minor swelling on knee after exercising with no pain? . i was playing soccer yesterday and i was running around and shooting like you would and for some reason at one point my knee started feeling weird. there was no pop or anything. i went home and then the knee started to feel really stiff and tight i can't fully bend it since it feels like it's going to explode. extending the knee also feels weird. there was a bit of pain yesterday a few hours after but now i feel nothing. i've never had any knee problems and i'm 17. what could this be?
you might have injured your knee joint while exercising. this is giving you stiffness and tightness. rest to the joint and application of pain balms/spray will reduce the symptoms.
