Ex. big toe,middle of front of foot and a red blister like rash on the upper side of my big toe.. also white blister like on from of my big toe. my pinky toe has a raised blister like bump. and my toe nails feel like they could easily pull off. I'm tired of smelling ammonia when I take my boots off..
