This is very interesting, I got a pain around the area
between the MTP joints of the 2nd and 3rd toes which made me limp, but being 4 miles from home I ran through the acute pain and it did get better (duller). A bruise came out on the top of my foot, but not on the bottom! This has happened several time since and I've nearly always been able to run the next day without pain. I've had x-rays, nothing fractured and I haven't let it stop me running. The bruise (and pain) is about 1/4 inch up from the webbing between the 2nd and 3rd toes.
