Itching on the palm of the hand may be related to the working environment, as well as external stimulation, fungal infections, and other factors. Patients need to be treated according to the cause under the guidance of a doctor.

1. Related to the working environment: If the hands are in contact with water, mud, or sand for a long time, it can lead to eczema on the palm of the hand, accompanied by symptoms such as itching, red spots, and blisters. Medications such as calamine lotion, antiperspirant and anti-itch cream, and Pimecrolimus cream can be used under the guidance of a doctor.

2. External Stimulation: Long-term contact with certain chemicals can make the skin dry and cause itching symptoms. It is necessary to avoid direct contact with chemicals and wear gloves to alleviate the situation.

3. Fungal Infection: Not paying attention to hand hygiene can lead to fungal infections, which are manifested as peeling, blisters, and itching. Topical antifungal ointments can be used for treatment, such as Terbinafine Hydrochloride Cream, Miconazole Nitrate Ointment, and Amorolfine Hydrochloride Cream, etc.
