My husband works in landscaping and since it has gotten very warm he feet get extremely sweaty. It causes a rash on his feet that resembles diaper rash. It also causes some swelling. It is also very painful. Once he showers and it starts to dry up the rash is even more very painful. He has seen a physician but no one really knows what it is or what to do with it. He was told not to put anything on it. He has tried different shoes and socks but it doesn t help. If he is off a few days the rash will go away but leaves angry dark purple scars for a few weeks that eventually fade away. Do you have any suggestions of anything we could try to get him a little relief? Thank you for your time.
