You have the same problem as me.

I have swollen ankle,foot and leg on my left side.But my right side is fine.Its sore sometimes when i walk on it and Throbs with dull aches and even get pins and needles in my toes

It swells worse in the evening because I have been on my feet alot during the day.Looks like someone got a mallet and hit down on my foot it looks that bad sometimes. My Temperature is fine and my face or hands havent sweeled up,so it isnt Pre-eclampsia.

I am however carrying alot fo excess fluid,so thats probably whats doing it
