Before seeing a Doctor or running off to some ER, if you are not having shortness of breath than you could try an ‘over the counter’ diuretic sometimes called a ‘water pill’ found in drug stores. They can help. I have never taken one myself but people say that they offer some benefit.
If you are SOB (short of breath) then medical help likely is in order.
I always thought SOB meant something else.

I always say short of breath when I mean short of breath. Why would that need an acronym?
