Thank you for your query.
It is not unusal to have heart burn and soar throat following retching
. This can continue for a while. As the medicine has effect for a short period it is better to discuss with your doctor who may suggest some antacids.
Viral infections can take some time to get controlled.
I hope I have answered your query to your satisfaction.
Wishing you an early recovery.
