Diagnosed with asthma as adult

Hi everyone,

I became very short of breath in 2021 and after a pulmonologist diad PFTs, physical exam and methacoline challenge, said I probably had asthma. I've been on a maintenance inhaler.

My question is, have other people who were diagnosed as adults given this tentative diagnosis, rather than just being told they have asthma.

The few adults I talked to who were diagnosed with asthma as adults said there was never any question they had asthma.

i understand there's no definitive diagnosis but when other doctors see in my chart "probably asthma," they are not sure I have it.
