I would like to know what causes swelling in the feet. My foot started to be swollen, I think, 2 weeks ago. It was all swollen and under my toes was hard like wood. When I got home, I applied Savlon which reduced the swelling considerably. Now, the underneath of my toes is not swollen, but the skin on top of my foot is a little bit raised, swollen more like it. The thing is, I can still walk and it does not hurt. It s just odd. It never happened to me before, I find it a riddle. Could you give me some tips? Thanks.
