Sneezing and a cold triggered by the slightest touch or irritation to your nose usually points to allergic rhinitis rather than repeated true infections. The nasal lining stays overly sensitive to dust, smoke, perfume or temperature change, and that sets off the cycle each time.
Next Steps
Rinsing your nose with a saline spray daily and noting which triggers set you off (dust, pollen, strong smells) helps cut down how often this happens. An allergy panel can pin down the exact trigger if it keeps recurring.
Health Tips
See a physician or ENT specialist if you get thick discolored discharge, facial pain or fever, since that needs separate treatment.
