I have an inflammated knee and it hurts like crazy. I cant bend it or anything. It is really hard for me to walk up and down the stairs. I already showed it to the doctor and everything, but my parents still want to send me to school. How do I convince them I cant go because my school has a lot stairs? I was thinking if I could make it looked swelled up. Does anybody know how to make it looked swelled up? Thanks for your help and really need the answers FAST!
