Help! need to know if there's such thing as seasonal asthma?

Absolutely: Most asthmatics have allergies and sometimes it is a seasonal thing. Pollen, grass, ragweed, flowers, etc can be "triggers" to an attack. Make sure what "trigger" you have and work with your physician to minimize exposure (air-conditioned bedrooms etc) and sometimes a non-sedating antihistamine may be helpful. Don't self medicate, talk it over with your physician. Good luck.
