I just totally twisted my knee. I turned around in a swift fashion, but my right foot was caught in between a tank and the wall. My body moved, my leg didn't, and I twisted my knee in a horrifying manner. There was a very audible snap, crackle and pop. What should I do with my Rice Krispy knee now? Also, anyone have a possible diagnosis? I can limp around, but it hurts like hell. I feel like an idiot.
