DEAR DOCTOR K: Last year I developed deep vein thrombosis (DVT) -- blood clots in my legs -- during a long international flight. One of the clots got loose and went to my lungs. I'm fine now and am off all medications. Is it safe for me to fly again?
DEAR READER: Yes, you can fly again if you take some precautions. Before I describe them, though, a little background information is in order.
