Jayde, at first I too thought my foot was just sore. Remember I joked about starting my new job and my feet not being accustomed to wearing shoes?
I am not supposed to do anything that puts excess pressure or weight on the foot until I am completely pain-free, and I understand that could be up to 8 weeks; I think I'm at week 4 or 5 now. It was an internist who made the diagnosis and he thinks I should see a foot orthopedist or sports medicine specialist to make sure it's healing properly and to prevent future occurences. The internist knows I like to exercise and was preparing to train for a triathlon, so that's why he thinks a visit to a specialist would be beneficial.
I had also read something in the past about certain shoes making feet weaker. Both my mom and aunt have had problems with their feet, which I want to avoid. I loved how my feet felt after doing yoga, so decided to lift weights barefoot, thinking it would help strengthen my foot bones, joints, and muscles. To get an answer to this question is probably a good reason to see a specialist. I also go barefoot around the house and in my garden as much as possible (thus the joke about wearing shoes to work ... had been out of work for 10 months).
Anne, my doctor thinks it's probably from overuse. As I mentioned above, I was preparing to train for a triathlon but hadn't even started running yet. And I had worked out a schedule in which I would increase distance or time by no more than 10% a week. I've had some bad experiences in the past with over-training so learned what my body can tolerate -- or at least I thought so! But your comment about diet gives me much to think about. Eating wasn't so great around the time I began to feel the pain; just started the new job and was a little too frazzled to prepare healthy food for each meal. As I get older, I am starting to see that diet is so, so, so important. Sigh.
Thank you both!
