I would say poor air quality is probably a problem. Even with the AC on this will cause me problems.

Question about your inhaler: Do you use a spacer device? If not maybe you aren't using it correctly? They can be tricky to get the hang of for some people (especially newly dxed adults and children). The albuterol really should help with the tightness and SOB.

Steam (from a shower) and humidity actually make me feel much worse so I don't know that I would reccomend that. Hot tea and black coffee with help sometimes. Don't have dairy untill you are feeling better.

I agree, maybe talk to your doctor about a short burst of prednisone. That would definitely help.
