Greetings. Thanks for the query.
This presentation can be seen with many diseases. This is limited information to make precise recommendations. The best option is to consult a Dermatologist to understand the condition. A thorough evaluation if necessary should be done. HIgh AEC counts indicates an allergic reaction but not necessarily to food but it can be to anything like clothes, personal use products. There are certain non dermatological conditions also where it can be raised. Reports have to be interpreted based on the clinical condition. Hope it helps you.
Your dermatologist will decide a treatment plan for you after a consultation.
u should avoid nuts like cashew , walnut, groundnut ,chocolates containing nuts as these are known allergens . also u can do other food allergen tests to find out other allergens .also consult a doctor who would help you to bring AEC down
