What kind of skin allergy do i have my is itchy usually at night and looks like a chicken skin?

Based on your description of itchy skin that appears like chicken skin, particularly at night, it's possible that you may have a condition called eczema. Eczema, also known as atopic dermatitis, is a common inflammatory skin condition that causes dry, red, itchy, and scaly patches of skin.

Here are some common symptoms of eczema:

1. Itchy skin: Eczema is often associated with intense itching, which can be worse at night due to increased humidity and warmth.

2. Dry and scaly patches: The affected areas of the skin may appear dry, rough, and scaly. They may also look like small bumps or patches of chicken skin.

3. Redness and inflammation: Eczema can cause redness, inflammation, and swelling of the skin.

4. Oozing and crusting: In severe cases, the affected areas may develop blisters that ooze fluid and form crusts.

5. Lichenification: Chronic eczema can lead to thickening and leathery texture of the skin, known as lichenification.

Eczema can affect different parts of the body, including the face, elbows, knees, arms, legs, and neck. It's essential to consult a dermatologist or healthcare professional for a proper diagnosis and personalized treatment plan. They can accurately identify your skin condition and recommend suitable treatments to help manage and relieve your symptoms.
