I wish I could get away from medications, especially the corticosteroids. But so far I am not able to get away. The closest I came was exercising 4x a week. I wasn't able to keep up that pace and when I got sick once (Upper respiratory) I was knocked down again. I have done yoga and it helps me feel clear in the chest for awhile after. I find that running or other exercises like that make my chest hurt until I am completely warmed up. I like slow starting exercises better.

Try to start a journal of your symptoms. You will be able to see a pattern. Mine is triggered by allergies, cold air, too much humidity, too little humidity, perfume, strong scents, cigarette smoke, vaping or e-cigs, running or too much activity too fast. Also eating too much too late in the day triggers me to be short of breath. Also stay away from those scented plug ins, I cannot breathe with those. Scented candles, or fragrant items such as room sprays are a no no. Car smells are also a no no. I will get a red chest and wheezy. I use fragrance free body wash, shampoo and face wash and lotion.

Also if you have allergic asthma get a report of the local pollen count. Even if it looks nice outside, it could be a high pollen count. I was having a hard time one day doing anything and it turns out the pollen count was DOUBLE that day. I also get allergy shots weekly, which sort of helps.

Hope this helps!

Here is the pollen website.
