this is the first time I have noticed this condition and we just came back from a vacation and drove 10 hours straight.
Uh... the symptoms are that your feet and ankles swell...
There are so many things that can show up as swollen feet and ankles. In general though, it means that your body is holding in more fluid than usual. It could be anything from pregnancy to a heart condition. Best to ask your doctor. Blessings.
