DEAR DOCTOR K: I've had four bouts of "bacterial sinusitis" over the past several months. How can I kick this infection for good?
DEAR READER: Sinusitis is inflammation of the sinuses. Everyone has sinuses, and many of us are not happy about that. Like you, my sinuses frequently get inflamed. Sinuses are the moist air spaces behind the eyes, forehead, nose and cheeks, on each side of our head.
