Thanks Dr Rohatgi. I do use coconut oil before bath , this eczema has been since 5or more yrs. Used lots of creams, coconut oil, aloevera gel. It reduces but due to hot weather or whenever my body gets warm and even after sweat it occurs,  inflammation and itching tendancy which leads to pain thereafter. Acne areas are specific, upper arm, thighs, inner and side knees, inner elbow and calf muscle (sometimes).
