It went down today but the pain is still there. I see my doc weekly right now so I'll see her tomorrow.
I definitely would call yr doc right away. It happen to me before but once I elevated my foot the swelling went down.
It can be a sign of something worse, particularly if only on one side... Get it checked out as soon as you can...
I read that if one is more swollen than the other if may be a blood clot or something. Call your doctor.
