Your conditions sounds like ezcema which is an inflammatory skin disorder. It is commonly associated with a food allergy or intolerance. I would start by eliminating wheat and dairy for at least a two week period to identify the food that my be causing it. Also a good fish oil supplement would help that has at least 500 mg EPA and 300 mg DHA. If you have a history of antibiotic use I would also recommend a course of a good probiotic that has a broad spectrum of bacteria including bifidobacterium at least 8 billion units. Adding curcumin (turmeric) may be helpful as well.
