Alright, so a couple days ago I started feeling a slight pain in my knee. I paid it no mind but I thought it was weird how there was no bruise and no swelling. Today though, I realized it hurt a little more since I had been outside for a while and I walk aroud at school all day. I started to limp a little as well.

I don't play sports and I don't recall hitting it on anything. Does anyone have an idea what's going on with my knee? I would appreciate an answer. Thanks.
