a couple days ago i apparently hurt myself at practice. nothing hurt until the next morning when i got up. its my lower ribs on the right hand side its been two days since it started hurting and a little bruising is starting to show up. i know i didnt get hit cause i havnt taken any hits for a couple of weeks now but neither ice nor heat are making it hurt less. anyone know what it is and how to deal with it and how to prevent it from happening again?
