Fingers appear red spots for no reason?

Fingers appear red spots and itch for no reason, which may be caused by many reasons. One possible reason is as follows:

1. Dermatitis or eczema: Skin inflammation may cause erythema, itching and pain. This may be caused by contact with irritating substances, allergic reactions or humid environment.

However, there may be other reasons why red spots are accompanied by itching symptoms, such as:

2. Insect bite or insect bite: Some insect bites can cause erythema, itching and pain. Such as mosquitoes, ticks, ants, etc.

3. Excessive dryness of fingers: Dry skin may cause erythema, itching and pain. In dry weather, when you wash your hands frequently or use too much detergent, your fingers often become dry.

4. Skin fungal infection: fungal infections such as nail vitiligo or onychomycosis can lead to erythema, accompanied by itching and pain.

If your fingers are red and itchy, you'd better see a doctor. Doctors can provide you with accurate diagnosis and appropriate treatment according to the specific manifestations of symptoms and physical examination results.
