My chest keeps getting tight and uncomfortable breathing, needing extra use of my inhaler. Wouldn’t be such a problem if salbutamol/reliever inhaler worked, but the period between being 40 and 60, while my asthma was well managed, with no need for a reliever inhaler, it stopped working. Found out when I was really poorly and prescribed a nebuliser with ventilin. None of the good effects, just the horrid side affects. All I can do is take extra doses of my preventer inhaler. Helps, but takes time. Fortunately I don’t get acute attacks these days, just a long slow decline over weeks. Funny how long term health issues present themselves over the years.
