According to Healthline, small red bumps on the skin can signify acne or allergic eczema. Red bumps can also indicate scabies, scarlet fever or skin cancer, so it is always best for individuals with unusual bumps on the skin to consult with a physician.
WebMD explains that cherry angiomas also present as small red bumps on the skin. The bumps most commonly develop on the trunk of the body. Cherry angiomas do not usually require treatment but should be removed if they cause bleeding or discomfort. Treatment options include laser removal or cauterization, a process in which a physician utilizes a special electric probe to burn off the affected tissues.
