Years ago I broke my little piggy to the point it was sticking out 90 degrees: ER doc just yanked it back in place and sent me on my way. About a month ago jerked it out, MAY have broken it, all sorts of colors but not displaced. I gave up marathons (well, I did ONE
) but run about 5 miles 3-4 times a week. First time after this last incidence it was noticeable, especially going downhill. Within a week or two not noticeable. But I just jog along at 9-10 minute miles now. If you had a real break I wouldn't expect to finish a marathon without substantial pain and/or inflammation. Good luck!
