How to manage pain and ankle swelling after a long flight?

Hi doctor,

I am a 25-year-old male, height 5 feet 8 inches, and weighing 155 lbs. I took a very long flight and developed some minor pain and swelling in both my calf and ankle. Three years prior, I had a DVT, in which the pain and swelling were so severe that I could not physically walk, and I was in extreme pain for weeks. So, when this minor swelling and pain from the long plane ride came about, I was a little worried but figured I had to wait a day or two to see if the pain and swelling got worse, as it did not compare even slightly to what I experienced in my first DVT three years prior. A couple of days went by, and both the swelling and pain had completely gone away. I thought I was in the clear and proceeded to take my next flight. After the short flight, the swelling in mainly just my ankle came back shortly after, followed by some relatively minor pain. I then proceeded to wait about four days for the symptoms to subside again, which they did not. So, I went to the local hospital, got an ultrasound, and consulted with a doctor. The doctor proceeded to tell me I had developed another DVT, but when I mentioned, "Is it possible that what you are seeing is the old DVT? As I am confused as to why the pain and swelling are so minor", he seemed a little unsure if he was just seeing the old clot that I had developed years prior, or that along with a new one. Even though the tonality and body language I was receiving from him were not too confident, I, of course, still proceeded to follow his directions, Xarelto 15 mg twice a day, no working out, and no flying any time soon. I have been taking the Xarelto for a week now, and the swelling and pain are completely gone again. Now I am in a predicament, in three days where I am supposed to stay the rest of my time here (about two months). My question is, If I wear compression socks, am still on the blood thinners, and am taking a small propeller plane with a flight duration of probably 40 minutes, Is the risk of this potential new (one to two-week-old) clot breaking off or getting worse high? Or do you think I'm probably okay to fly? Yes, I could take a ferry and bus to get to my location if needed, but I am really not wanting to do that because the duration of that would be nine hours or more. Also, not sure what I am going to do when it comes time for me to go back home as the 25 hours flight back is a lot more intimidating. Please help.

Hi doctor,

Thank you for the second opinion; I will definitely look for a hematologist in the next area I am going to.
