You are recommending inhaled steroids. When you do that you should also mention the enormous harm it can do to your health. I got off that poison three years ago and switched to natural anti-inflammatories. They work better and there are no side effects. As to what Advair did to me - osteoporosis, adrenal fatigue, candidiasis, and on and on. The candidiasis alone would have killed me if I had not been treated in time.
Have you talked to your doctor about the increase in symptoms? You may need to add a daily medication to lower the overall inflammation in your lungs or up the dosage if you are already taking them. Examples would be advair, flovent, symbicort etc.
I second the anti-inflammatories they help the immune system overall - fish oil or flaxseed are the typical ones.
My respiralogisted recommended a couple different vitamins - vitamin D (2000 IU daily), vitamin C (2000 IU daily), N-acetyl cysteine (1500mg daily), CoQ 10 (60mg a day) and fish oil (2000mg daily). The vitamin D, fish oil and N-acetyl cysteine may help you because they all help the immune system and the last one helps thin the mucus and is a powerful antioxdiant.
Hope that helps!
You may also be suffering congestion. In that case you need a mucus thinner/expectorant. Buy an over-the-counter preparation that has guaifenesin, preferably only guaifenesin. Take a tablet and drink a full glass of water. It helps greatly. In fact the worst episodes I have with asthma involve serious congestion.
You can also start using natural anti-inflammatories. These help greatly and thee are no side effects. As to diet, be very careful about sweets and too much starch. These cause a proliferation of Candida albicans. Candida worsens asthma and allergies.
I almost forgot. If you can find chewable bromelain, use that. Very, very helpful.
