Hi, Please get the Allergy
Profile of your son done, by which you can exclude allergy to any other food product or dust or drugs. Wheat exclusion from his diet shoud be complete, ie Roti, puri, parathas, bread, pizza, cakes ,pastries,dalia, sooji upma, noodles etc should be totally avoided.
This will reduce his IgE levels.
For skin peeling, apply moisturisers or coconut oil liberally, twice a day.
Pranayam or deep breathing will be very helpful.
