Going to the Dr. first may be the best option. My son has chronic problems too, but in the beginning I made it worse by using over the counter products for athletes foot - it seems my son is allergic to one of the common ingredients in these creams and actually made the rash blister as if his foot was burned. He is also allergic to the tea tree oils and my dermatologist told me that we should stay away from these products. Unfortunately, my poor son has inherited my very sensitive skin. Good luck.
