Most of the time he is facing fungal infection on his toes and in between toes. After using anti fungal powder it recovers. During pandemic working from home but facing red red patchy type spot on his ankle and legs. It comes and after some days it turns to black n that skin looks so hard n dry. No itching no expanding. No other part of body. Only on toes and legs. Why this happens. Blood test report is also normal . Kindly tell.
