Why Do Red Bumps Appear on My Hands, Causing Both Pain and Itching?
The most common cause of red, painful and itchy bumps on the hands is skin allergy. Skin allergies mainly occur in spring due to contact with pollen, and there are many allergens. People with sensitive skin should take preventive measures. Additionally, these symptoms can also be caused by eczema and urticaria, which are skin diseases caused by fungal infections and can recur and spread.
Verruca vulgaris, also known as a wart, is a small, painless, and itchy bump that grows on the surface of the skin. Flat warts are slightly raised above the skin surface and are slightly darker than the surrounding skin. They usually do not cause significant harm to the skin and may disappear over time. Some warts may be larger, such as those with a semi-circular shape, and may be the size of a green bean or half a soybean. These warts are also painless and itchy and can be transmitted through self-inoculation, making them contagious.
Skin allergies often occur when the skin frequently comes into contact with allergens such as pollen, proteins, chemical irritants, or ultraviolet radiation. This can lead to the formation of small, raised patches on the skin. Some patches may be very small, resembling the size of a bump, while others may cover a larger area. Regardless of their size, these bumps are often both painful and itchy. If you notice such bumps on your hands, they may be caused by a skin allergy.
Eczema and urticaria are skin diseases caused by fungal infections. When these diseases occur, they can lead to the formation of small bumps on the skin that vary in size. Some bumps may be as small as a bean, while others may be larger, with diameters reaching five to six or even seven to eight centimeters. If the bumps on your hands have a tendency to spread, are spherical, and produce a white powdery substance when squeezed, you should be cautious as they may be indicative of eczema or urticaria.
