I'm experiencing this weird feeling in my left knee: on the lower inside edge of the knee, (just below and to the right of the patella I can feel something that ... shouldn't be there, or that i've never felt before. It feels kind of like a tendon or something moving where maybe it shouldn't be. I'm experiencing no pain, and sometimes I can't feel it at all, but it will come back after engaging in certain activities that I suppose are putting stress on the joint(such as sliding down wet grass).
Other symptoms; there's been no noticeable swelling, and the 'weirdness' is most noticeable when my leg is slightly bent and i'm lifting it forward. keeping it locked out seems to mask it. I believe it was caused by having the knee cave inwards
I'm gonna go see a doctor/physio, but i wondered if someone might be able to shed light on what might be.
