My left knee hurts like mad! I didn't bang it anywhere, i just woke up today and it is killing me! If i sit and try to get up it hurts like crazy to straighten it or if i am standing and try to sit down and bend it, it's a throbbing pain now spreading thru my leg. I took a tylenol but dont know what it could be and i have to work a double shift tom. that requires walking fast nonstop
Does anyone know what this could be?
