Why is my entire palm swollen and itchy?

The entire palm may experience symptoms of swelling and itching, which may be related to factors such as skin intolerance, dietary irritation, psychological tension, contact dermatitis, and urticaria. Management may involve skin protection, dietary regulation, psychological therapy, and medication. It is recommended to visit a hospital to determine the exact cause and follow medical advice for treatment. The analysis is as follows:

1. Skin Intolerance: Prolonged exposure to sunlight or other external irritants such as chemicals and extreme temperatures may lead to skin intolerance, causing swelling and itching in the palm. Protective measures should be taken, such as avoiding prolonged sun exposure and using sunscreen or an umbrella for protection.

2. Dietary Irritation: Consuming excessive spicy or irritating foods and alcohol may cause swelling and itching in the palm. Avoid spicy foods and alcohol. Increase intake of fruits and vegetables appropriately to maintain a balanced diet.

3. Psychological Tension: Psychological factors such as heavy work pressure and mental stress may lead to swelling and itching in the palm. It is recommended to relax, reduce work pressure, and engage in appropriate physical exercise and recreational activities to relieve tension.

4. Contact Dermatitis: Contact with certain exogenous irritants or allergens may trigger contact dermatitis, resulting in swelling and itching of the palm. Patients should use medications such as Loratadine Tablets, Mupirocin Ointment, and Clobetasol Propionate Cream under a doctor's guidance to aid recovery.

5. Urticaria: Urticaria is a type of allergic skin condition caused by allergens, characterized by dilation and increased permeability of small blood vessels in the skin and mucous membranes, which may cause swelling and itching in the palm. It is recommended that patients use medications such as Chlorpheniramine Maleate Tablets, Binghuang Fule Ointment, and Calamine Lotion under medical guidance to alleviate symptoms.

In daily life, it is important to keep the hands clean and dry, and avoid contact with allergens and irritants.
