I once suffered an extreme ashma attack, this required paramedics to come out as I had not had an attack since I was a child and had recently moved down south so did not have an inhaler on me. Essentially had an ambulance out at around 3 in the morning and they had shove a tube down my throat to keep my airways clear and pump oxygen, this blasted me with a few puffs of anti inflammatory steroids and after about 30 minutes I was fine. But they advised for me to go to a doctor and get my blue and brown inhalers.
So I register with a GP and get an appointment and go to see them. The dude was some Asian with a super thick accent, could hardly speak English. He point blank said he didn't think the attack I had that had required an ambulance was related, and said I didn't need an inhaler. It was the first time I had an argument with a medical professional but it ended in with me stating I was entitled to inhalers because I was asthmatic and they where preventative even if the symptoms where not currently showing. He begrudgingly wrote it out and I got my inhalers.
Honestly even years later I still remember how stupid that response was, thank god I have never encountered anything like it again. I actually ended up moving again, it seems that due to the fumes in cities it sets my ashma off after extended periods of time, now that I am back in the country I have not had an attack for well over a decade.
