I'm a 55 year old woman, in good health.  3 days ago, I started getting pain on the top part of my left foot.  I suffered a foot injury about 5 years ago.  It's painful walking and by the end of the day there is swelling on the top of my foot.  What could it be?
pain and swelling over top of foot is due to hairline fracture of any bone of foot. take rest, apply foot bandage and start some anti inflammatory and pain killer.
