The warm weather officially has arrived! Trees are blooming and the scent of freshly mown lawns is in the air. But for those of us with asthma and allergies, spring also means trouble breathing, itchy eyes and lots of sneezing. Do you have trouble catching your breath when you’re exercising or are around people who smoke? Does your child struggle to breathe or cough a lot when he or she plays outside or with the family dog? You and your child might be one of 300 million people worldwide who suffer from asthma.
