Hello C.,
You've gotten great advice so far. by any chance, could your son be allergic to latex? latex allergy can show up as delayed reaction as asthma. Has he been tested for allergies? when going to the allergist, ask him about using magnesium to help with the asthma.
I helps my daughter big time. I mean that instead of 15 days of breathing treatments, she needs ONE day of breathing treatments. I don't know if your son would have the same results. Also, I did not just stop her medication when I gave her the magnesium. I had her checked by her doctor and I even used a stethoscope at home to make sure she was not wheezing. I also noticed that when she had asthma she was also constipated. 1 tsp milk of magnesia mixed in her strawberry milk has done wonders for her. Magnesium is a bronchodialator and in conjuction with treatment can help.
I googled: asthma magnesium here is the link:

Good luck and definitely check w/ an ENT and allergist. ~C.~
