Symptoms you have experienced....

I recently ended up in the hospital and am trying to figure out what happened. I recently was diagnosed with asthma, had a cough for about 2 months.
This week, I experienced two episodes. Here were the symptoms for the first one: started with a cough, tunnel vision, felt as if I could pass out, ended up tachycardic (sp), had pressure in my chest and my whole body became full of pins and needles. I also felt itchy but didn't see big hives..... redness though.

2nd episode...I was discharged and only three hours later, ended up with a bad cough, took inhaler and ended up in severe body tremors and tachycardic again...taken to emergency room...and cardiac work-up was done again. Discharged as possible allergic reaction to inhaler.

Any adults who have experienced anaphylaxis, do the above symptoms possible point to that?

I have a child who is anaphylactic to things so have only dealt with this as a parent.

Thanks for any feedback.
