Bumps or blisters on the bottom of my foot

Alisha

I’ve been getting these off and on for years, and they’ve never really bothered me enough to go to a dr, but I’m curious now as to what they are. It starts out as one bump then four or five more will cluster with it and kind of blister up. They itch like hell for a day, hang around for a week and then dry up and fall off. They only appear on the bottom or sides of my right foot and I usually break out with them more in the summer. Any ideas? I might ask at my next annual app if I remember lol.

Yes I know my foot is dry. It’s winter time in Indiana. No amount of lotion helps lol.
