I used to have severe asthma but then I got told I had outgrew it.. lately Ive been getting out of breath at random times and I have to take deep breaths but it makes me dizzy. I can only sprint for about 10 seconds without feeling like im going to collapse. Whats wrong?
What's your age? Do u regularly take inhalers? With spacers. If not, then take fluticasone propionate 250 mcg, formoterol fumarate dishy Chat Doctor.  Take montelukast 10 mg at night. If u were already taking these then do a PFT and consult your the nearest pulmonologist.
