Injury on back of knee

Patient

Q: Hey there! I was out surfing today and got run over, which isn't too uncommon. The fin hit the back of my knee, but instead of a bruise there's a long raised bump. I'd say it's raised about a millimeter or two, and three and a half inches long or so. It's red and doesn't look like much aside from that, but it's causing me to limp quite a bit, and hurts if it's moved past a few small angles. It's soft and doesn't hurt unless I press down on it and touch the muscle (?) beneath.
