I Am Wheezing Today And Have Been For About Three

I am wheezing today and have been for about three nights in a row. I am 76 years old. It doesn't bother me except for at night when the sound can keep me awake. Also in the day I cough more than usual. Should I consider a medication? Should I avoid going outdoors? Hate to do that but grass polens do bother me and we are in that season.
