From the foods that we eat, to the chemicals that we are exposed to daily, to dustmites & pet dander. It can take a detective to work out which particular allergens are triggering eczema. Although proper allergy testing can be extremely useful for detecting life-threatening allergies such as nut and egg, they are also notoriously unreliable in finding the root cause of eczema flare-ups.
Keeping a symptom diary can be a great way of becoming aware of any potential eczema triggers. The more details you record, the easier it will be to spot any potential allergens. This includes food & drink, detergents, creams, pollen, fabrics and rapid changes in temperature. Against each day, rate your symptoms from 1 to 10, with 1 being good and 10 being very severe.
