Hi Gordon, I'm 33 years old and have diagnosed with 3 DVT's in my left leg which resulted from back surgery and temporary paralysis. I work for an aiarline and travel every month. The pain can be extreme sometimes in my case and I always have to spend dome time elevating my leg when i get to my location. Always wear your stocking while flying. It really helps, I have done both and it makes a difference. I have one question for you. Are you still experiencing pain now that you are on the warifin? And what is your dose. I was at 9 mg a day for a very long time.
