Re: Could this be asthma -heart related -or weather?
It could be asthma. My son has exercize induced asthma. He also gets attacks when he's outside in the cool air for too long.
If I were you, I wouldn't wait till your doctor gets back from vacation. I'd see whoever is taking her cases until she gets back. If it is asthma you're suffering from, it's VERY SERIOUS and not to be taken lightly. It only takes one attack to kill you. Sorry to be so blunt but it's true.
