I just went through the same kind of thing, same location. It gets better, then worse. At times, kind of scaley at times. Mine was eczema caused by a food allergy to eggs. I took a dose of Benadryl and rubbed some 1% cortisone cream on the affected area, and it improved greatly. That is what tipped me off that it was probably an allergic reaction. I had a good hunch it was eggs, since I had been eating an awful lot of eggs prior to that. I cut out the eggs, and it cleared up right away. Every time I cheat and eat eggs it comes back.
