You have allergies
Let’s get to the obvious reason you can’t stop sneezing out of the way first. “Sneezing is caused when a foreign particle or irritant hits the nasal tissue,” explains Miguel Wolbert, MD, of West Texas Allergy. “You sneeze in order to forcibly remove the particle from the nasal cavity,” he says. In an allergy, your body has an overreaction to something normally benign, like pollen from plants or animal dander. If sneezing comes with other classic allergy symptoms like a runny nose, congestion, and itchy eyes—especially if you go outside or are around the family cat—then it’s most likely allergies. If not, then it’s something else. As far as what that could be, read on. (Learn about never-thought-of-them ways to treat your allergies this spring.)
It’s a sinus infection
Both allergies and a cold can turn into sinusitis, an infection that causes sinuses to swell. Symptoms include postnasal drip, facial tenderness, coughing, fever, and fatigue, according to the American College of Allergy, Asthma & Immunology. Luckily, most sinus infections are usually viral and you’ll feel better in about a week, says Dr. Wolbert. But if sinus infections keep coming back or are associated with allergy symptoms like a runny nose or chronic sneezing, he says there is a good chance that allergies are the main cause of the sinus infections. Treating the underlying cause—in this case, allergies—will help solve your problem. Find out just how bad it is if you hold in that sneeze.
