Thanks for coming to HCM. Sorry to hear about your father's condition. You should take him to the physician as he needs good physical examination. You did not mention if your father had external injury
on chest too, also if any pleural tapping was done. I am assuming here that he was negative for rib fracture
. He might be developing some infection at the injury site too. Please tell us the details of CT scan
report and any other tests done. Also, please tell us age of your father, any diseases he have & if he is taking any medicines including aspirin
. In any case, he needs to visit physician.
Wish your father get better soon.
