Looking at a picture that was mentioned in another forum (http://gobarefooting.files.wordpress.com/2010/04/foot-muscles.jpg
) I'm experiencing pain on the extensor digitorum for my second toe. Received it while running the Hospital Hill 1/2 Marathon in Kansas City. Before this I had run up to 10 miles without any issues. I started experiencing discomfort around mile 8 and pushed through (probably unwisely till the end). The pain was more prominent on landing and then rolling through to the ball of my foot for the push off. I can bend and wiggle my toes without any pain, but if I take my second toe and bend it back towards my ankle, lots of pain.
Since Saturday I've kept my foot elevated when I could, iced it, and wrapped it in castor oil. There was minimal swelling which has gone down. Slight discoloration. It's tender to the touch, but not too bad. I can stand on that foot, but as soon as I shift my weight to the midfoot/forefoot, lots of pain. Current plans are to continue resting that footso no running activities.
Any ideas of what it could be: bruising as opposed to stress fracture? This is the second day after the injury and there isn't much swelling at all. Foot looks almost normal. Top of the foot is a little pinker than normal.
