What are the common symptoms of eczema?

The symptoms of eczema are characterized primarily by itching, redness, and dry, inflamed skin. Eczema, also known as atopic dermatitis, often presents with a rash that can vary in appearance depending on the individual and the severity of the condition. Itching is a predominant symptom, often leading individuals to scratch the affected areas, which can exacerbate inflammation and lead to further skin damage.

Redness occurs due to increased blood flow to the area as part of the inflammatory response. The skin often becomes dry and irritated, reflecting its impaired barrier function which is a hallmark of eczema. This combination of symptoms makes option A the most accurate representation of common symptoms associated with eczema.

The other symptoms listed in the other choices can refer to different skin conditions. For example, blisters and pus-filled sores are more indicative of infections or conditions like impetigo. Brown spots and leathery skin could be associated with chronic skin damage or sun exposure, while scaling and hardening of the skin may be more characteristic of conditions like psoriasis. Thus, while these symptoms are related to skin issues, they do not define eczema as clearly as the symptoms of itching, redness, and dry, inflamed skin do.
