I have these weird blisters in the toes of both feet. They are small and seem full of liquid, surrounded by irregular redness and sometimes almost purple. Some numbness, occasional itching. They dry up, form a scab and fall off and it heals. I had it last year and went away with an antifungus cream (after a whole month) and daily warm salt feet baths. What is it? Why did I get it again?

You may be letting your feet get too much moisture and not drying them off completely and thoroughly.

Now, let me ask if you are diabetic? This is a VERY important question.
