My legs are swollen big at the foot and ankle on both the legs. I traveled from out of country and was sitting for more than 30 hours. That made my legs swollen. Also, I had a family emergency and I had to stand for a day and a night. Didn't sit or rest for a while. So my legs are swollen at the ankle. I elevate my legs while sleeping and the swelling reduce in the morning when I wake up. Then during the day, it will swell again and ankle become big before end of the day. I didn't see any Dr yet. Does this requires any treatment? Keeps swelling like this for a month now. I have burning sensation on the foot. Swelling in the ankle on both leg. Do I need to ask for any scan or xray.
