What should I do if my hands are very itchy after peeling shrimp?

Generally, itchy hands after peeling shrimp may be caused by shell irritation, residual juice, seafood contact dermatitis, urticaria (hives), or damaged skin barrier. It is recommended to seek medical attention promptly, identify the underlying cause, and under a doctor's guidance, improve symptoms through general management, medication, and other treatments. Specific causes are analyzed as follows:

1. Shell irritation: Fine spines or bristles on the surface of shrimp shells can physically irritate the skin on the hands, causing itching. Immediately wash both hands thoroughly with running water and gently rub with mild soap to remove any remaining spines. Avoid touching eyes, nose, or mouth with the hands.

2. Residual juice: Protein-rich fluids from inside the shrimp may adhere to the hands and irritate the skin, leading to discomfort. Wear disposable gloves when peeling shrimp to prevent direct contact. If juice does get on the skin, soak hands in saline solution for 5 minutes before rinsing thoroughly to reduce irritation.

3. Seafood contact dermatitis: An allergic reaction to foreign proteins in shrimp can lead to redness, itching, and often a burning sensation on the hands. Patients should follow medical advice to take antihistamines such as cetirizine hydrochloride tablets, loratadine capsules, or ebastine tablets, and avoid further contact with shrimp and similar seafood.

4. Urticaria: Worsening allergic reactions may trigger urticaria, characterized by raised, hive-like rashes and intense itching. Topical treatments such as calamine lotion, desonide cream, or mometasone furoate cream may be used as directed by a physician, along with oral antihistamines to relieve symptoms.

5. Damaged skin barrier: Individuals with naturally dry hands or minor cuts are more prone to allergic reactions and pronounced itching after contact with shrimp. Patients should use barrier-repairing agents such as recombinant human epidermal growth factor gel, ceramide-containing lotions, or vitamin E cream under medical guidance. During allergy flare-ups, additional antihistamine treatment may be needed.

Before peeling shrimp, apply a layer of petroleum jelly to form a protective barrier on the skin, or use specialized peeling tools to minimize direct contact. Avoid spicy and irritating foods temporarily to prevent worsening of skin itching. Keep hands clean and dry, and avoid scratching to prevent skin damage and secondary infection.
