I ran 5K in less than 32'50. I shouldn't have. I could not swim afterward because I couldn't stand the chemical'd water on the beds of the blisters. Should I be concerned that, three days later, they haven't crusted over yet? They've been covered with antibiotic ointment and huge band-aids since, but I walked a mile downtown on Thursday night, a half-mile to the tailor on Friday, and again around downtown yesterday. Perhaps I shouldn't.
