Potential asthma question

[Hercules12]

Hi
I'm 45 and in good health but in the past I have occasionally been prescribed blue and brown inhalers. This was originally when working on a chalk board and only if I get a prolonged cold and cough. I also have a dust mite allergy that exasberates this but it's well controlled by fexofenadine.
I was tested for asthma by using a peak flow metre. i still have one at home and can get 370 reading.
I'm fine at the moment and its irrelevant for work as I'm only working from home anyway.
I am worried though if I should have a prescription just in case as obviously dont want to get cv and be more at risk of problems. I also dont want to waste gp time. I have called receptionist and my records dont specifically say I have asthma.
Should I do anything or just leave it?

@Herculees12 - I have very mild asthma with a specific trigger - viruses that turn into upper respiratory infections will kick it off so I've only ever used my inhaler for that. Definitely not daily use. My current one expires at the end of May and I was able to get a telephone appointment with my GP (they've closed the practice as a coronavirus precaution) who prescribed one over the phone. You should be able to do the same?

thanks, Lillianfullstop. that sounds like me. I will wait till end of day tomorrow to see if I get response back from surgery or pharmacy and if not I'll call in wednesday.
