I've had mild asthma in the past...mostly wheeze free.

Mine tends to be bronchoconstrictive, but if there is little mucus build up or the constriction is mild, it can go unnoticed when listening to the the chest with a stethoscope. I rarely move into a full blown asthma attack... mostly when some particulate situation occurs in my environment. So I do carry an albuterol inhaler for those times.

I typically have more problems in spring, when the mold under the snow is exposed, and then there are windy days to move it around. Smoke also sets me off, any exhaust from vehicles, or a fireplace back up or cigarettes, etc.

Breathing with the stomach muscles instead of the chest really helps me. This type of breathing is recommended for people with anxiety as well.

Grapeseed extract is very good for reducing this mild inflammation that allergies can bring. It is also recommended for MS patients for their inflammatory problems. So do consider trying it. I use it every spring myself, 200-300mg a day.
