Question: My child has had a runny nose, sneezing, wheezing, and coughing for a few weeks now. I thought it was just a winter cold, but now I'm wondering if it might be allergies and asthma?

Answer: Great question! And the answer isn't always clear from the get go, especially at this time of year, when winter may still be hanging on (prime time for colds), but trees are blooming (and their pollen can trigger allergy and asthma symptoms). But there are ways to tell and it is important to know...
