My mom's 53 and she's got diabetes and this dust allergy thing going on. She randomly got short of breath today and couldn't talk, which panicked us a bit. She usually gets mild asthma when she's near dust, but today it hit out of nowhere with no dust around. After taking Asthalin, she felt better. I'm curious about what could've triggered this sudden asthma attack without being around dust, and is it okay for her to use Asthalin every day?
