Bumps are small, raised areas on the skin that can occur for various reasons. They may be caused by conditions such as allergies, insect bites, or skin infections. Bumps can vary in size, color, and texture, and they may be itchy or painful depending on their cause. In some cases, bumps can be harmless, like those from acne or minor irritations. However, persistent or unusual bumps may require medical attention to rule out more serious conditions, such as skin cancer or dermatitis. Proper diagnosis and treatment are essential for managing any underlying issues related to skin bumps.
