What is a common symptom of eczema?

Itching is a hallmark symptom of eczema and is often one of the first signs that a person experiences. Eczema, also known as atopic dermatitis, is an inflammatory skin condition that leads to dry, itchy patches on the skin. The intense itching can cause individuals to scratch the affected areas, which may worsen the condition and lead to further irritation, inflammation, or even infection. In addition to itching, eczema typically presents with red and dry patches, but itching is the most prevalent and distressing symptom that can significantly impact a person's quality of life.

The other options may be associated with different skin conditions or other instances of skin irritations. Painful blisters, for instance, are more characteristic of conditions like herpes or contact dermatitis rather than eczema. Red spots can occur in various dermatological issues but are not specific to eczema alone. Greasy skin is not a common symptom of eczema; instead, individuals with eczema often experience dryness rather than oiliness. Thus, itching stands out as the primary and most commonly recognized symptom of eczema.
