Did it years ago, went to memorial hospital. I think it was around 6K.
The problem with broken or cracked ribs is, if the fracture is relatively fresh it doesn't always show on the x-ray. Even if you got fractured ribs there isn't a lot they can do except to give you painkillers to ease the pain. The pain should get bearable after around five days and you can do your day to day things after around two to three weeks. Your body will tell you what you can and can't do through pain. If you can't feel an abnormality by touching your chest you should be alright without going to a hospital.
There is another way to detect broken ribs. A doctor takes a stethoscope to your chest and listens to your breathing. If they're broken there is a crackling noise.
