Why can I get blisters on my feet in summer and it itches!

Hello, your condition should be beriberi, not fungal infection. You can use foot bubbles once, and then use dakening for external treatment.

Suggestion:

Drink plenty of water at ordinary times, pay more attention to rest, keep a regular life, and have a light and digestible diet. Eat more foods containing vitamin C, such as tomatoes. If it is serious, you can take Risolao tablets orally and avoid spicy food.
