I sometimes hate feet. I mean, I love them but I hate them. lol I wore open toe shoes to help out at my son's scout camp. It poured the entire day and I had mud all over my feet. One foot, around my baby toe started itching that night. Probably 5 years later, it still itched. Same area. I had itched it until I made the skin course and raised. I tried about every remedy I could come up with. It finally went away. Doctor said I likely got some kind of fungus in the mud. Why just in that spot, I don't know but honestly, thank my lucky stars my entire foot didn't itch like that! I'm just sharing because you have a 'hot spot it sounds like. While I itched and itched, it took me ages to actually go to the doctor for it. I'd just go ahead and go. These are not blisters, correct? Actual bumps show up?
