Q How can I tell a cold from an allergy?
Dr. Knapp: The symptoms are similar, but if you have sneezing, a runny nose and congestion for longer than 10 days, you probably have an allergy. Most people tend to develop seasonal allergies in their teens and young adulthood. Symptoms often get better during the 50s and 60s, perhaps as the body's immune system ages.
Q I feel miserable. What can I do?
Dr. Knapp: Close windows and avoid being outdoors early in the morning and in the evening, when pollen levels are highest. When you come in from outdoors, change your clothes and wash your hair if necessary.
Antihistamines are available over-the-counter to dry runny noses; decongestants will help with congestion. Whether a particular antihistamine works depends on the individual. Prophylactic nonprescription nasal sprays, such as Nasalcrom, have to be taken every day and can be effective. Don't confuse them with decongestant sprays, which can make congestion worse if used for more than a few days.
Your family doctor can help you find the best medicine or combination to treat your allergies or offer prescription medications, such as nasal steroids. If you're only getting a little bit of relief, or if your symptoms continue all year-round, consult an allergist. New treatments are available.
Q What causes allergies in Pennsylvania?
Dr. Knapp: Our allergy season begins when trees begin to pollinate, as early as late February or March. The yellow or green dust you find on your car in the morning is pollen. Between April and the end of June, grasses such as timothy cause us the most trouble. Ragweed season starts about August 15 and lasts until the first good frost.
