It's always something. I have another infection on the bottom of my middle toe. I just got over one back in December. I don't have diabetes so now I've had test to evaluate my circulation. My feet swell a lot while sitting at my desk all day. My trip to my primary said my toe had gout(she never looked at the bottom of it) the podiatrist says that I walk with my toes curled downward causing it to callous and, as of late, get infected.
