Sometimes I feel a little clicking, what could that be? I've been playing basketball but very lightly and I doesn't feel like I hurt it since surgery. I'm alittle worried about this. Sometimes I feel like a stinging inside. Help! Sometimes people say I limp but I don't think i do and my brother says I don't but I don't know what to think. It doesmt hurt at all and isn't swollen. I have full range of motion. I'm just really worried.
