Need work up: In the form of RAST (Respiratory Allergen Serology Testing) and I gE. These blood tests would tell you and your allergist which specific allergens you are sensitive and reacting to. Pollen is only one of 2 dozen in the panel. Most common are cat dander, mold and dust mites.

See ENT: Do you have an anxiety issue? If so this may be from stress. On the other hand, you may also have an upper airway obstruction with vocal cord dysfunction a likely possibility. Consult an ENT doctor.
