I have a itchy, reddish circle on the bottom of my foot. it isnt scaley. it almost looks like a calase. any idea of what it could be?

Possible options: A callous typically doesn't itch too much, but it may just be that. Other options are the start of a blister, a mild fungal infection despite no scales, and a mild eczema. Best to have a doctor look at it to confirm. I would start with an over the counter anti fungal cream as you await your appointment.

Rash: On the bottom of the foot it could definitely be a fungus. One would need to see a picture to determine for sure
