Hello, Thanks for the query.
Any blunt injury
( punch is one of them) over ribs may have break ( fracture
) the ribs of your husband.
He was shaking due to injury and some what anxiety
. Now there is no anxiety and no fear but after effect of injury are there.
He might have got some fracture in rib(s) because he is continually c/o pain during breathing , laughing , coughing.
These all parameters are suggestive of # in ribs , so please get a X-rays of effected part and rule out any internal injury.
Good luck , have a good married life. Dr. HET
