Name changed, as this post could be outing.
I developed asthma as an adult in my late 30s. I have always suffered from various allergies but I wasn’t asthmatic. That changed when I began to notice that my chest would ‘tighten up’ in bed at night, and I would struggle to breathe normally. These episodes would pass after 20 minutes or so, and I would cough up sticky mucus from my lungs.
During this period, I caught a nasty respiratory virus and was struggling to breathe for several days. I went to a NHS walk-in centre where a nurse gave me a ventolin inhaler and suggested I try it. Two puffs later, I could breathe normally. I was diagnosed as an asthmatic.
I was able to control my asthma well with ventolin for the next few years, then when I was 42 the asthma became much worse very suddenly and the ventolin wasn’t touching it. My GP then prescribed steroid based ‘preventer’ inhalers and steroid tablets which didn’t have much effect. By now my asthma was getting genuinely scary. After several very difficult months, the breakthrough came when I was prescribed a combination inhaler containing a long-acting bronchodilator and a steroid. I have taken this every day since, and will probably continue to do so for the rest of my life. I can now live a normal life as long as I take my inhaler daily which goes everywhere with me.
My suggestion, OP, is that you ask your GP for a ventolin ‘reliever’ inhaler and a ‘peak flow meter’. This is a plastic device into which you exhale and which measures the rate at which your lungs are able to breathe out. You will then be able to measure your own lung function and get to know what is normal for you, and work out when & why your breathing is problematic and what your ‘triggers’ are. Everyone’s triggers are different. Asthma is a pain and severe asthma is extremely serious and frightening but it is controllable with the right medication.
Apologies for the essay, OP. I hope some of it is useful, and
I’m happy to answer questions or clarify anything.
