A doctor will usually be able to discern whether your skin condition is eczema or another similar condition. If normal eczema treatment does not provide relief, you may be referred to a dermatologist to identify the root cause of the condition. As eczema is often associated with an allergic response, you may be advised to have an allergy test. Common allergens linked to eczema symptoms include mites, fungal spores, pollen and some foods. In the case of food, certain changes may need to be made to the diet.
