Hi Maisie,
I am 34 - also had asthma as a child. It returned when I was 28 and that is EXACTLY how it returned for me. Chest tightness, difficultly breathing deeply. That is still how it is today - I am on Flovent (2) puffs (2) per day and
Ventolin for rescue. I do not cough and I do not wheeze. I just get SEVERE chest tightness and have trouble breathing - A LOT... It is scary and I hate it.... Most people who hear do not believe that I have asthma because they cannot 'HEAR' it - but I FEEL IT...
Good luck to you - make an appointment with a Pulmonologist for a Lung Function Test - it will all be ok
