Hi ! It is good to see that you did a very good observation work on your boy friend after the head injury
. The vomiting
might have been related to the head injury, but the diarrhea
is not related to the head injury. Both the vomiting and diarrhea could be due to eating from outside resulting in food poisoning
. You can consult your family physician who may give him some appropriate antibiotics which will cure his present problem. Wishing him an early recovery.
