Denton sits in one of the heaviest allergy regions in Texas — cedar in winter, oak in spring, ragweed in fall. When allergy congestion lingers for weeks, it can turn into something else: a sinus infection.
How allergies lead to sinus infections
Allergies inflame the nasal passages, and swollen sinuses drain poorly. When mucus gets trapped, it creates an environment where infection can develop. That's why sinus infections so often follow right on the heels of allergy season in North Texas.
Allergies vs. sinus infection
Allergy symptoms tend to come and go with exposure — itchy eyes, sneezing, clear runny nose. A sinus infection more often brings facial pressure or pain, thick discolored nasal discharge, congestion that doesn't let up, and sometimes fever or a reduced sense of smell. Symptoms lasting more than about ten days without improving point more toward infection than allergies.
What a clinic visit may involve
A visit may involve an exam of the nose, sinuses, and throat, plus a review of how long symptoms have lasted and what was tried already. Because many sinus infections are viral and some are bacterial, the provider will explain which pattern the symptoms fit and what the options are.
