this is the 2nd time in 3 months that my legs have been swollen. the first time was on a car ride for about 13 hours. i did get out of the car a couple of times but not for very long..... the 2nd time was a week ago. i was on a plane for 3 hrs. only walked a little to the luggage. the swelling lasted about 10 hrs. the 3rd time was last nite after walking down up and down a main street browsing in windows. i have been trying to drink a lot of water and eliminate salt. what else can i do? i am out of town and not near my regular dr.
