Thanks, Trish. This, of course, is an unprofessional self-diagnosis, and only a possibility. Despite drastically reducing my running, hoping to rest the ankle as much as possible without compromising my running conditioning too much before the marathon, there's an area on the inside of my foot, below the ankle, that just won't get better. It feels okay to walk and do other things, but any running or jumping just gets it inflamed, and the day after I'm limping around again.
Last night, I decided to re-research my symptoms, and the description of a navicular stress fracture is pretty much spot on. The fact that this thing won't go away with the little bit of rest and recovery I've given it leads me to suspect something more than just some strained ligaments.
Yes, it could just be weakened ligature where the tibial posterior tendon inserts into the navicular, but if it's the bone itself that has a stress fracture, then that's probably going to require a boot or a cast and complete refrain from impact or load-bearing exercise for at least 6 weeks. I'm not even sure I should walk the marathon next Sunday.
I'll see my general practitioner this week and he'll likely prefer me to an orthopedist or physiologist. (shrug)
I hope I don't have to wear a cast. If I can't run, I figure I'll put the next 6-8 weeks to could use concentrating on spinning and swimming. 4th of July 10K is probably out. I want to run a half marathon in August though and start plotting my next assault on the marathon again around then or September. So I need to spend some time resolving this foot problem.
Thanks for the concern and well wishes. 3165 days ago
