i am in the middle of a short tour from portland to eugene. two days, 130 miles or so. i can make it obviously, but i would still like to know whats going on. so late afternoon yesterday, my achilles tendon on my right leg right around my ankle area just started hurting really badly. hurt pedaling, hurt walking, etc. i have been popping lots of tylenol, to no avail. anybody have any idea of what could be causing this? i have toured a lot in the past, but this has never happened to me before. thanks bf.
