the top of my feet get itchy and swollen in the winter. what foot infection do i have?

The simple fact that you probably wear thicker socks + enclosed warmer footwear in winter can increase your suceptibility to a fungal infection.  Other possible causes should be ruled out e.g raynauds phenomenon.  Seek advice from a Podiatrist

I have the same problem. Doctors have ruled out fungus/athlete's foot and I tend to go barefoot whenever possible because it is worse when my feet get hot. It has been a constant winter  cycle for about 5 year. The itch/swelling can be excruciating. It makes me want to move to a warmer climate. My pharmacist suggested diabetes. Please let me know if you have any answers I have been to several doctors to no avail! The only relief is soaking in cold water and then foot elevation. But I would like to know the cause.

I have the same problem since 4 years, I also feel tingling sensation and feel like stepping on needles when I walk. HAve you found relief??
