How Can I Tell the Difference between Hives and Eczema by Looking at Pictures?

Characteristics of Hives (Urticaria):

• Appearance: Hives typically present as raised, red, or skin-colored welts on the skin. These welts can vary in size and shape and may appear suddenly. They often have a well-defined border and can change location quickly.
• Itching: Hives are usually very itchy. The itching can be intense and may worsen with heat or pressure.
• Duration: Hives can appear and disappear within hours or days. They may come and go, often resolving without treatment.
• Triggers: Hives are often triggered by allergic reactions to foods, medications, insect stings, or environmental factors. They can also be caused by stress or physical stimuli like heat or cold.

Characteristics of Eczema (Atopic Dermatitis):

• Appearance: Eczema usually appears as dry, red, and inflamed patches of skin. The affected areas may be scaly or crusty and can vary in color depending on skin tone. Unlike hives, eczema does not typically have raised welts.
• Itching: Eczema is also itchy, but the itching may be more persistent and can lead to scratching, which can worsen the condition and cause the skin to become thickened or leathery over time.
• Duration: Eczema tends to be a chronic condition, meaning it can last for weeks, months, or even years. Flare-ups may occur periodically, often triggered by irritants, allergens, or changes in temperature.
• Location: Eczema commonly affects specific areas of the body, such as the inside of the elbows, behind the knees, and on the face or scalp, especially in children.
