A month or two ago I fell playing basketball and it made a popping noise almost like it came out of place. my leg was weak feeling and I put ice on right away I could walk and everything okay still just week feeling. the next day my knee was twice the size of what it normally is. The swelling immediately went down the next few day but now everytime I bend to a certain point it like catches on something and lately it s been hurting doing simply things like getting up or walking down stairs and I ve also started running which might be part of it. I was looking at the runners knee and another diagnosis but I m still not positive but I want to know soon so I can get it healed as soon as I can!
