Hi uncentain,
Hope you're feeling better and that your appointment with your doctor went well! I think as everyone else suggested below, you definitely want to have an asthma action plan moving forward because when it escalates, sometimes you can't help but have high anxiety so it can keep you calm to have an "emergency" plan.
You may want to get a personal nebulizer as this helps the albuterol (or whatever you're using as a rescue inhaler) get into your lungs quicker for a better relief.
If I'm having an acute asthma attack (for example, when my fingernails turn blue) I always go straight to the ER. However, even if it doesn't feel like it's "that bad" of an attack, it is
always always always better to be safe than sorry and you should
never feel sheepish about popping into the ER for your asthma.
Something else I've found helpful, is that my doctor has equipped me with a "spare" prednisone treatment (I'm experienced with prednisone, if you're new to this type of steroid you definitely want to be under your doctor's supervision using it for the beginning at least). This way, if I'm having a "seasonal" asthma attack (i.e. change in weather, allergy season, etc.) that I can't seem to kick, but not severe enough that I need to go to the ER, I can give myself a prednisone treatment to relieve chest tightness and take the swelling out of my airways. Now, be forewarned, prednisone is not always a fun drug to be on (some side effects I've experienced are increased appetite and rapid heart rate) but it's well worth it to be able to breathe!!!
Hope that sharing my "action plan" will aid you in discussing some options with your doctor!
Happy Breathing : )
