How can you tell if you have an allergy to pollen?

Seasonal symptoms: Most people with pollen allergies have itching, sneezing, running nose mostly outside and with varying severity throughout the year. If symptoms are worst in a consistent season, like may-june, pollen allergies are highly likely. Some pollen allergic people will also have other allergies, though, and this may vary the timing of symptoms. An allergist can help sort it out.

Allergy test: Pollen allergy can be suspected on clinical grounds if you get itchy eyes and nose, runny nose, congestion and sneezing when outdoors in certain seasons. To really make a diagnosis, though, you need to have a skin test or blood test showing the presence of ige antibodies to pollen.
