Nasal Allergies. Neti-pots and saline washes are a great start. Oral antihistamines are of little benefit for most patients, and many have spurious side effects. Best to see your local friendly allergist to find out if you have allergies and methods to help improve (avoidance, meds, allergy shots, etc).
Nasal allergies. Sealing your nares stops the sneezing because allergic responses occur primarily when the nares are irritated. Try using a neti pot twice daily, add quercetin to help and or an over the counter allergy medication.
