Hello, I have a sports medicine question. On Monday I ran (and finished) the Boston Marathon. In the last several miles I started to feel some pain/discomfort on the outside of my foot, right under my ankle bone. I didn't think much of it at the time, mostly because I just wanted to finish and both my legs were killing me. However, when I finished and started walking that random pain turned into 8-9/10 sharp pain whenever I picked up my foot. I went to the medical tent and a podiatrist told me that I had tendonitis of the peroneus brevis and not a stress fracture of the 5th metatarsal (best news I heard that day) My question is this: I know I should rest my foot, but that is almost impossible considering I need it for walking. I'm wearing a good pair of hiking boots today, and that stability combined with a whole lot of Tylenol, Aleve, and a Salonpas (topiccal analgesic) patch has the pain down to 5-6/10. How do I immobilize it further? Any advice would be much appreciated. Thanks!
