Then I remembered that I had a physical therapy session that afternoon, so I figured I would get the therapist to look at the toe instead of waiting for a few hours for an ER doctor. Once at PT, my physical therapist took out a tuning fork and did some vibration tests on the toe. She quickly determined that the toe was not broken! A wave of relief flooded over me. However she said that I needed to take a few days off for the pain and swelling to subside. Naturally that means I had to DNS my 5k on Saturday, but it was the best prognosis I could have hoped for!
Presently, I am chomping at the bit, anxiously awaiting my return to running. It's like I am tapering for a marathon. My legs are super well rested and I have been getting more sleep than ever. Everything is lining up for a great "restart" to running, I just have to wait for my stupid toe to feel better.
