So there are these two little extra bones under the big toe and they can get irritated (so I've now found out). This is sesamoiditis in a nutshell. I guess it isn't terrible news. I was given an orthotic to wear increasingly more until I can wear it all day - that will take some of the weight off that joint of my foot. Sounds like I can run as long as I can put up with the pain. As it was never too bad to run, my 15k trail race this Saturday is definitely a maybe right now.
(This "pain" began 3 days after my 50k, during my second recovery walk)
More guest's this weekend and next week - so back to sporadic posting when the computer room is free.
