I am a middle-distance runner, averaging about 25 miles a week. After running ~20 miles in 48 hours (slightly higher than normal, but nothing crazy!), I noticed that my right foot, though painless and experiencing no direct trauma, was showing huge bruises on the medial side, with the darkest spot on the middle of my arch. The next morning, my foot was swollen and the bruising was visible on the lateral side of my foot as well. However, I've experience no pain at all! I haven't tried running on the foot as I am afraid to give myself an overuse injury. What could I have done to myself?
ANSWER Hi Lisa, Obviously you bruised your foot (you did not need mt to tell you that), but the concern here is why. I am assuming you wore the same running shoes and traveled the course that you normally do. You are correct, you did not seem to do an excessive amount of mileage, so why the bruising? Without having the luxury of being able to examine you, I do not know what is going on. You have two options. You can wait a few days until the bruising improves, or you can see a foot specialist now to try and determine why this is happening. Certainly, if you wait it out, then go running and the bruising recurs, then you should definitely see a foot specialist to determine the source of your problem, if for nothing else, to make sure it is not a sign of a problem.
