I broke 2 ribs in thé front 2 years ago and I still am in pain.
On April 20th I broke 8 ribs...there's nothing they do for it except pain killers. They don't wrap anymore because higher chances of pnemonia. Dr told me, no matter how they heal is ok because they're still protecting your internal organs.
Your husband needs to do deep breathing exercizes to prevent pnemonia.
I also had blood in the lungs and fluid on the outside of the lungs as well as a lacerated spleen and a broken wrist. You probably should get him to the Dr's in case there's more internal injuries.
3 months later and I'm still not sleeping in my bed.
Good luck
