Hello, darling! Well, it depends. I've broken my ribs three times.
The pain can be intense at first, followed by very shallow breathing. It can then settle down for a few days, providing you take it very easy.
The pain is sharp and brittle, and located fully within the area of damage.
It's then quite usual for a resurgence of pain about a week later, before it heals. This can be quite crippling.
Why do you ask?
