About four weeks ago, I went to bed in perfect health and woke up with a sore foot. Within 24 hours the pain was excruciating and lasted for about 2 weeks. I was completely incapacitated for about 4 days. After 4 weeks, the pain has just about gone. I went to the GP about it, but I don't think she had a clue. I've broken bones in my foot before, and it felt exactly the same. I had an insect or spider bite on my foot, so she diagnosed infection and gave me antibiotics. I'm pretty sure that something broke or got otherwise damaged, as the pain from a break normally lasts about three weeks. Two days ago, I went to bed in perfect health and woke up with the other foot a bit sore. Now, 24 hours later, the pain is excrutiating. There's no position I can put my foot to lessen the pain. It's a little swollen by my big toe and it looks a bit crooked. What the hell is going on. I've heard of stress fractures from pedalling too hard, but does that happen in the misddle of the night? Interestingly, both these events happened on the day after I got my best time on my normal 5 mile sprint, but younger roadies come past me pretty fast, so I'm not pedalling that hard. I'm very depressed about it. I had a 40 miler planned for today, but I've got no chance.
