Sinus infections are colds gone wild?

A recent Newsday article just discussed something that a lot of sinus sufferers already know all too well.  “It's not unusual for the common cold to morph into a sinus infection. Most cases of acute sinusitis start with a cold that inflames the sinuses, and that leads to a bacterial infection that may last up to four weeks.”  And, real sufferers know – it can last months.  And, something that lasts for months and happens 4-5 times a year;  that’s more than a math problem.
