This is likely Candida, I had it for many years. I took coconut oil 1 table spoon a day and the itches are gone. coconut oil killed the outgrowth of yeast inside my body which is the founamental cause of my skin problem. I saw a few doctors before, they offered no help to treat the cause, but gave me steoid to mask the symptom. Yeast infection is a wide spread problem. But the doctors do not have this information in their mind, I wonder how my doctors missed this. We as patients really have to look after ourselves.
