Last night i was at cheer practice and while I was tumbling, i landed on my ankle/leg weirdly. It hurt a little whenever i landed, but the pain was not too bad. I kept practicing and my whole leg would hurt when i would do certain things, but it was not too bad. By the end of practice, i could not walk on it at all without tons of pain. I iced it this morning, and last night and also took advil this morning and last night. Today my ankle, knee, and thigh area are swollen. I can put some weight on my leg without too much pain, but I can not walk normally without TONS of pain. I have had problems in the past with patella tracking, but it has not bothered me recently.
