I have had red circles with a white dry area appear on my body since I was a child. They appear on my trunk area most of the time; however, recently I have had the circles start to appear on my scalp, face and had. The circles in my hair is a real issue because of all of the flaking and itching. The one on my had looks gross. When the circle goes away I am left with zero pigment on my skin. The circle normally takes a couple of weeks to run its course. However, when I get a lot of them I do not feel well i.e. sick at my stomach, anxious, very exhausted. Help me get to the bottom of my problem.
