Hi my names Claire, I ve been getting itchy patches which start on the top of 2 toes which then after few days turn into brown spots with liquid, then dry out and leave me with hard skin this healed then came back again but also on side of inner foot below big toe. I ve tried athletes foot powder spray and sprayed all my shoes, I keep my feet clean and ensure they are dried before putting socks on. What do you think this is and how can I prevent it?
