question: Yesterday I tripped on the sidewalk and crashed onto the concrete. The first thing to hit was my knee cap it hurt like crazy but I was able to get up and walk home. It swelled pretty significantly and I could hardly walking on it within a few hours. I took two Alene and have iced it. Today is better but am limping and if I torque it a little there is shooting pain. Still icing it and I have braces from a former acl tear (years ago) and a knee wrap. Should I give it more time? Is it important to see a doc sooner rather than later?
