Chances are this is just a cleansing reaction. My old Naturalpath once told me that a lot of skin problems are the result of toxins stored in the skin being released. He also said a lot of this toxins are from an excess of grains in the diet. If your old diet consisted of a lot of breads,pastas and other starches and grains, then this probably a cleansing reaction. Keep the area clean and dry and avoid chemical around the inflamed area.
