re: Anyone had any dealings with a blood clot in your leg?

Have you tried putting on a TED hose of the affected leg? Should help with the swelling.

For all of the alarmist out there, he already has an IVC filter, which should catch the clot before it can go to his heart and subsequently his lungs (causing a pulmonary embolism).

I would have them repeat the hyper coagulate workup. If it was done right when you had the clot, it may not have been accurate.
