Can post nasal drip cause fever?

Drip alone won't give u a fever, but if u have a bad sinus infection or a cold, that will definitely cause one. If your temperature is high, pls take some rest, drink warm water, and see a doctor instead of ignoring it.

My son gets this post nasal drip every winter, but we only see a fever when it turns into a throat or sinus infection. We keep him hydrated, give warm steam inhalation, but always consult his pediatrician if his temperature crosses 100 degrees.

I once thought my fever and drip were just a mild seasonal allergy, but it turned out to be a severe sinus infection that required antibiotics. If you have a high fever, severe headache, or facial pain, please don't wait and see a doctor immediately.

I totally get it, dealing with a constant throat drip and a fever at the same time is so exhausting. The drip itself doesn't cause the fever, but the infection behind it does. Please take some steam, drink warm soups, and rest well.

Post nasal drip is a symptom, not the root illness. If you have a fever, it means your body is fighting off an infection like flu or sinusitis. It is always safest to get evaluated by a physician to get the right treatment.
