This is not common at all, but after the parathyroid procedure, a few people might notice that you need to cough up extra mucus for a few days. Less than 1% of our patients have this problem, but they all tend to think it is a problem so they call us. This is not a problem. This is normal and is not a sign of infection or any other kind of trouble.
Drink lots of water to keep the mucus thin also makes it go away faster. Big picture, we operated on the inside of your throat. It will be sore a little and cause some extra mucus. This is not a big deal and not to be worried about. If it lasts more than a week or is associated with a fever, then consult your physician–this won’t be related to the operation at all.
