Itching burning redness swelling in toes only during winter months. also tiny blisters and then peeling. disappears in other seasons. what is this?

Fungus: I would first try a topical antifungal. It may happen in winter months as your feet are in socks and boots and therefore a nice environment for fungus to thrive in.

Chilblains: This is probably chiblains. You should see your dermatologist for a correct diagnosis.

Raynauds: This can be a number of things. Raynauds, allergy to your winter shoes, neuro dermatitis. I suggest you get evaluated.
