question: I was on a long flight from JFK to Istanbul, 9 hours. My ankles were swolen, one went down the other has stayed since March 8, it is now April 25 and there are red spots on my ankle. I saw a Dr. in Venice about two weeks after the March 8th flight who sent me to the emergency room. They did a blood test and said nothing indicated anything serious. I think it has improved a little, I got a blood thinner from the pharmacy, approved by the Dr. in the emergency room. I am now ready to go by bus to Prague, 2.5 hours and after a week, fly to London from Prague, 2.5 flight. Should I wear compression sox? This is on my right leg. In 2012, I broke the femur on my left leg and had blood clots after the surgery - all is healed now. I am an American artist and have been in Europe on painting residencies in Venice and in Cesky Krumlov, CR. I am in Cesky Krumlov, CR now till Monday. Do I need to go to the emergency room? I appreciate your help and suggestions. Thank you very much, Ms. Willie Marlowe 1/17/1943
