Every night my right foot and ankle swell up and my toes feel tight. I had pre-eclampsia when pregnant it's a similar feeling to the oedema I experienced then. But why would I only get it in the evenings and why only one foot?
I have exactly the same problem and also had pre-eclampsia in my first pregnancy(21 years ago),I doubt the two things are connected though :-)
My doctor said it is fairly common in people who spend a lot of time either standing at work or sitting in the same position for too long at a desk. I would ask your doctor for advice though as swollen feet/foot could be a sign of circulatory problems and they may want to do an ECG to check your heart.
