So, I fractured my foot. Not in the Summer plans!
Embarrassingly, I was just walking. I had recently gotten back into aerobics and went on a brisk walk Saturday morning. My foot hurt, but I figured I was just being a wimp for being out-of-shape. I kept walking and the pain intensified. I iced it a few times over the weekend, but was not going to pay an ER bill for a sore foot.
Monday I went to the local Walk-In Sports Clinic. They said the 5th metatarsus was fractured. I have a boot (thankful they didn't give me a cast and I can take it off to shower and swim and sleep) and I have to use crutches as my pain guides me. He recommended using them for a week or so until foot not sore and then keep the boot on until I see him in a month.
