Trotter Foot

I think a trip to the doctors might be needed as my left foot is very swollen I have experiencing pain on my left ankle bone for a while just thought I had bumped it on a chair or table at work but it doesn't seem to be easing and I always suffer from swollen feet in the evening as I spend a lot of time on my feet during the day but even after resting it for the night it still seems quite swollen so I think I need to go and get it checked out.
