How to deal with a busted rib?

It’s been a week now since I hurt my ribs. I went to the hospital and they didn’t even check it, they gave me no pain killer and they sent me home. So seeing a doctor is out of the question. Breathing, coughing, laying down, sneezing and dressing myself is very painful. There are no obvious signs of bruising or anything broken, nothing feels out of place, but the pain is severe. What ways can I help it to heal faster? It’s already been a week and no improvement.
