Possible Exercise Injury?

Lalleshwari

For the past few weeks now I've had pain on the top of my right foot. No bruising or swelling, and it's fine when I walk or go running but when I touch my foot it feels painful in a kind of bruised way (not sharp or extremely painful, just mildly so). I don't have any recollection of doing anything to it, but I'm slightly worried as it doesn't feel quite right and I don't know whether it's worth going to see my doctor.

Has anyone had this before or know what it might be?
