Why does it itch more the more I scratch it?

Generally, increased itching in the genital area when scratched may be caused by clothing friction, excessive local cleansing, or skin conditions such as eczema, jock itch (tinea cruris), and contact dermatitis. If concerned, it is advisable to seek medical consultation promptly. Detailed explanations are as follows:

1. Clothing friction irritation: Wearing rough-textured or tight-fitting clothes that frequently rub against the skin in the genital area can cause itching. Switching to soft, loose, breathable cotton clothing can reduce skin irritation and friction.

2. Excessive local cleansing: Frequent use of harsh cleansers or overwashing the genital area can damage the skin barrier, leading to itching. Choose mild, non-irritating cleaning products, limit washing frequency, and avoid vigorous scrubbing.

3. Eczema: The skin in the genital area may develop eczema due to internal and external factors such as damp environments or allergen exposure, resulting in redness, papules, and intense itching. As advised by professionals, topical treatments such as zinc oxide ointment, hydrocortisone butyrate cream, or mometasone furoate cream may be used to reduce inflammation and relieve itching.

4. Jock itch (tinea cruris): Fungal infection of the groin and surrounding skin causes ring-shaped red rashes with papules and blisters at the edges, accompanied by significant itching. Under a doctor’s guidance, antifungal creams such as terbinafine hydrochloride cream, bifonazole cream, or miconazole nitrate cream should be applied to inhibit fungal growth and eliminate symptoms.

5. Contact dermatitis: Allergic reactions in the genital skin may occur after contact with chemical substances, plants, or other allergens, causing redness, swelling, and itching. Following professional advice, calamine lotion, halometasone cream, or triamcinolone acetonide acetic acid cream may be used to alleviate allergic symptoms and reduce itching.

In daily life, maintain cleanliness and dryness of the genital skin, avoid scratching to prevent infection. Eat a light diet and avoid spicy or irritating foods. Maintain regular sleep patterns, a positive mood, and strengthen overall immunity.
