Having allergies can definitely promote breathing problems! I have had allergies all my life, but just developed breathing problems this summer. Like you, I have more problems during hot, humid weather. A trip to the doc confirmed that my asthma symptoms were likely being caused by my allergies. I am on Advair now, and my breathing has been much better. You will likely Advair (long-term medicine) and Proventil (to take puffs in "emergency situations")prescribed to you.
