I live in a hilly urban place and twice in the past two weeks, I've been walking up one of the main uphill roads and talking on the phone and it's been HARD. Chest feels tight. Had to pause today and take a deep breath. Friend at other end of phone said I didn't sound out of breath.
I did a peak flow test and it was average. Nothing special.
Should I be concerned?
I do a lot of weights in the gym but less cardio these days. Could that be a contributing factor? Am I just out of cardio shape?
It worried me a bit.
