i got punched in my kidney area about 5 days ago. the pain has calmed down, but it still hurts to walk, lay down, and i will even wake up during my sleep because there would be pain. when i touch where my kidney's at there will be pain in my lower back too. i am not urinating blood though, but i've been leaning to my left side to prevent pain also, and thats starting to mess up my back. what has happened to my kidney? how can i help it? and how can i prevent messing up my back?
