I fell tonight at gas station. i was liting my leg to go over the hose to the pump, already connected to tank. however, my left foot got caught and i literally flipped over and landed very hard. first onto my knee and then my right elbow. pain to my knee was significant and I broke a severe cold sweat. i took my time geting up into my car before taking a look. scraped up but swelling was occurring with focal burning at the inferior portion of the patella and possibly tibia too. my elbow looks like and egg is stuffed inside and to he touch feel also, very painful. I cannot hardly bend my knee and when i try to bend my elbow it sparks a tingling,burning pain
