Pain is not responding to Arnica or Advil and there's some swelling at the base of the toes. Perhaps I can try an analgesic that starts with a different letter of the alphabet. Though short-term it won't be much use, as it appears I have given myself a stress fracture, says Wayne. All that enthusiastic walking coming up on the toes and going from relatively little walking to walking over two miles from carpool to the office and from the office to the bus was too much too soon. Treatment: immobilization! Wayne recommends going back to a crutch -- waaaaaah!
Good news is that it doesn't affect my riding. Because soles of cycling shoes are very stiff, they don't allow the foot to flex and the foot is effectively immobilized. A silver lining.
