Seriously if you're in about your 30's and your foot just seems to stay sore, ask your doctor about gout. (It's one of those things that often seems to get overlooked but my dad could have written the primer on it. Beer, STRESS, certain nuts, certain veggies are all triggers. My dad ended up on crutches many an autumn due to stress-triggered gout during corn harvest.) Of course, if you had an injury or something else, ignore me. I love online diagnosis.
