How to treat seasonal allergies as an asthmatic
Visit an allergist.
An allergist can help diagnose what is causing the worst of your asthma symptoms. Seeing an allergist is particularly recommended if you have severe, daily asthma attacks, if you have severe seasonal allergies, or if you need help figuring out what your symptoms are.
Also, if you've been in the hospital because of asthma, you'll likely need to see an allergist. Ask about being tested for allergies.
