I m sneezing. I have a stuffy, irritated nose. Nasal allergies cause the lining of your nose to become swollen and inflamed. When you have this type of allergy, you have a runny nose with a thin watery discharge, nasal itching and congestion, red, itching eyes, sneezing, and often drainage from your nose down the back of your throat. Your pharmacist can help you decide whether to see a doctor about your sneezing and congestion or whether to treat your symptoms yourself.
Many different triggers can cause nasal allergies.
For some people, dust mites, pet hair or dander, and indoor mold bring on sneezing, sniffling, and runny nose. Since these triggers are present all the time, these allergies are said to be perennial. For other people, pollen from trees, ragweed from grass, or weeds can be the culprit, and they usually have symptoms only during certain seasons. These people have seasonal allergies. A few people suffer from both perennial and seasonal allergies.
