When to go to Emergency?

When to go to Emergency?

I'm kind of new to asthma. I have been distraught with it this last week. For instance, yesterday I had three or four attacks, with my feeling like it was closing, one last night and so far one attack today,

I have a blue and an orange inhaler and am just hoping I'm using them properly. I've watched Tube demos but it is difficult to know if it's getting into the lungs.

Thanks for letting me share this.
