i think if i had a punctured rib i would know. but this has been hurtin in the morning and during the day im fine for a while but last night it started hurting bad and i cried like a little girl (no offense to little girls) but im an ex-army ranger. also my left arm mostly finger tips are numb. i am going to the doc tomorrow for an x ray
so you don't mention why you have not been to a doctor to have x rays.
The biggest problem to watch out for with rib fx is whether a rib is displaced and poking into a lung.
As for pain, I actually fractured a rib once. The pain at night could be unbearable but it wasn't so bad during the day. I think its easy to imagine how lying down on your back or side would affect a broken bone. Because you are weight bearing on the fracture, the pressure itself and moving around in the bed can cause increased inflammation and pain.
Once you are cleared by an MD, you could try wrapping ace bandage or finding out how to tape the ribs to decreased movement at the fracture site.
