Just like two intersecting streets, allergies and asthma are two different entities, but like the crossroad they can intersect and be present together in many patients where the allergy is a direct cause of the asthma symptoms. If you think you have allergies you need to see your doctor. Sometimes the symptoms of allergy are difficult to diagnose, for example, asthma symptoms can be mistaken for chronic bronchitis and nasal symptoms can be confused with sinus problems. The most accurate way to diagnose allergies is by seeing an allergy specialist who can administer specific allergy skin tests to determine if you are allergic and to what specific things you have allergic responses. Sometimes it is hard to tell the difference between an allergy and a cold.
Colds tend to be more of a problem during the winter months.
My grandson has been diagnosed with asthma. The majority of asthma symptoms in children occur before the age of 5 years. It is extremely important that your grandson be properly treated with anti-inflammatory therapy on a regular basis to prevent recurrent asthma attacks. Despite the common belief that children outgrow their asthma, which is often said by pediatricians, in fact the thing that most children outgrow is not their asthma, but rather their pediatrician. Most of the adults I see had asthma as kids and the ones who do most poorly are the patients who have not been appropriately treated as children.
