I tried to do peak flow today (we happen to have a meter in the house) but on my best effort I could only get 310.
The second thing is every time I do it (a fast breath into the metre) I make a loud barking sound and my lungs burn for a bit after.
I remember doing peak flow years ago and also not being able to get past 310 ish mark. I think that I also made the same loud noise. I am unable to do peak flow without making the noise unless I blow slower into it but I get an even lower reading.
I don’t have a diagnosis of asthma (my dad does). I don’t hear any wheezing or chest tightness at rest or when running (though occasionally others have said I wheeze when running)
I have a on and off feeling of air hunger for the past 2 months (it started after a mild case of covid) I have put it down to anxiety which I also have. My gp just said it was common after covid.
Do you think I should go back to my gp about the low peak flow reading and noise I make when exhaling into it? Even though I have always had a low reading/made a noise when completing it..
My sister has had a lot of lingering lung and throat problems after having Covid, so I’m sure it’s to do with that.
Having said that, I had nasal polyps and asthma, and when I completely gave up sugar and most carbs, they went away and I hardly needed my inhaler at all. Might be worth a try?
