Anyone have asthma?

Ba

So I caught a cold since monday. I also have asthma and this cold won't go away. I cant shower pick up my kid or do any physical work without having a asthma attack. The Dr said I'm fine just take nyquil. That doesnt help with my shortness of breath she says oh just take your inhaler. I've been needing my inhaler every 12 minutes. Is there anything to do to lessen this chest tightness. A warm shower didnt do much for me.
