spoke to soon?

lovely ride today, and lovely swim. i'm tuckered out, which is to be expected, but my foot is so sore which i didn't expect at all! i did a fair amount of running in the water, could that be it? maybe i hit the bottom funny dropping in to the shallow end, and didn't notice with the water to "catch" me? in any case it felt almost like a strain when we got out of the pool, at one point i thought my toe was swelling (but it wasn't), now it just has that same burning in the middle of the sole of th ball, which i had forgotten about, but a flood of memories are coming back... think i'll try to keep it elevated tonight.
