I have a ST Jude Aortic Valve, 2008. Friday I flew from Dubai to Boston and then Cleveland. Slept 12 hours, woke Saturday with lower GI distress. Very little movement Sat, Sun, Mon with increased movement today. When I woke this AM lower right leg has been numb. This evening its sore, 5 on 10 pain, or less. I am on Warfrin. Concern could this be a DVT? Does this need addressed tonight?
