Possible bone injury?
I had Osgood-Schlatters as a teen and have the signature OSD bumps at the top of my Tibia just below the knee. Today while playing basketball I fell and landed with all my weight on the OSD lump on my right leg. I heard a pop and it hurt like crazy, but I could walk so tried to just shake it off. Throughout the day however the pain got worse and what looks like a bone bruise knot formed (the size of a pingpong ball). Stairs are alomost impossible (I rely on the railing, without it I feel like I'm going to fall), driving is painful, and ice doesnt seem to be helping. Could I have fractured the top of my Tibia partially or something?
