Introduction
In general, small hollow pits on the skin accompanied by itching may be caused by allergic reactions, acne, folliculitis, eczema, scabies, or other conditions, and targeted treatment is required. It is recommended to seek medical attention promptly. If exposed to allergens such as pollen or cat hair, skin inflammation may occur, leading to papules and edema; excessive scratching may result in the formation of small holes.

In general, the appearance of small hollow holes in the skin accompanied by itching may be caused by allergic reactions, acne, folliculitis, eczema, scabies, or other conditions, and targeted treatments are required. It is recommended to seek medical attention promptly for proper diagnosis and treatment. Specific analyses are as follows:

1. Allergic Reaction

Exposure to allergens such as pollen or cat hair may trigger an allergic reaction, leading to skin inflammation, formation of papules and edema. Excessive scratching may result in small holes. Avoidance of these allergens is essential, and medications such as promethazine hydrochloride tablets, ketotifen fumarate capsules, or cetirizine hydrochloride tablets may be used under medical guidance to relieve symptoms.

2. Acne

Acne is a skin condition caused by blockage of sebaceous glands and hair follicles, resulting in bacterial infection. It may lead to redness, swelling, pain, and itching, sometimes with pus discharge. Acne can leave scars or hollow holes in the skin. Treatment may include medications such as erythromycin ointment, sulfur ointment, or tretinoin cream, based on a doctor's advice.

3. Folliculitis

Folliculitis is an inflammation around hair follicles, usually caused by bacterial infection, which may lead to accumulation of pus within the follicles. After the pus drains, small holes may form. The infected area may also present with redness, swelling, pain, and fever. Treatments may include fusidic acid sodium ointment, mupirocin ointment, or compound polymyxin B ointment, used under medical supervision.

4. Eczema

Eczema is a type of skin inflammation that may cause redness, swelling, and itching. Excessive scratching may even lead to skin ulceration and the formation of small holes. It is recommended to follow medical advice and use medications such as clobetasol propionate and gentamicin sulfate cream, zinc oxide ointment, or calamine lotion to alleviate symptoms.

5. Scabies

Scabies is caused by infestation with the scabies mite. These mites burrow into the skin, creating tunnels that appear as small holes. Intense itching, especially at night, may occur, along with fine linear scaling and tiny red spots visible on the skin.

In daily life, maintaining a light diet, keeping the affected area clean, and drinking plenty of water can help promote healthy skin recovery.

Can patients eat shiitake mushrooms during a cold?
Mushroom consumption is temporarily not recommended for cold patients who have a history of mushroom allergy or who experience severe gastrointestinal symptoms (such as vomiting or frequent diarrhea) during the cold. Allergic reactions may cause discomforts like skin itching and difficulty breathing, worsening the condition. When digestion is impaired, the dietary fiber in mushrooms may increase the burden on the gastrointestinal tract, exacerbating symptoms such as bloating and abdominal pain, which is unfavorable for recovery.
