Dark bumps on your skin appear for many reasons, according to Family Doctor.org. While some bumps are harmless and won't require treatment, others may indicate a serious health condition. Learn about the types of dark bumps that commonly appear on the body to help ensure your well-being. Notify your doctor before trying any home remedy for skin conditions.
Significance
Your skin is the largest organ on your body and offers an abundance of room for small bumps to form during the course of a normal lifetime. MedlinePlus reports that in most cases, dark skin bumps pose no threat to your health, especially if the bump is soft and rolls easily under your finger. Other dark bumps may signal cancer or a dangerous infection and should be examined by your doctor as soon as possible.
Types
Plantar warts are a skin virus signaled by hard bumps with dark dots -- usually on your hands or feet -- that don't itch or cause other discomfort, according to MayoClinic.com. While over-the-counter medication can relieve most warts, in some cases your doctor will remove the virus through freezing. Notify your doctor if you spot warts in your genital area, which could indicate a sexually transmitted infection. Small dark bumps on your face, back or chest may be a form of acne called blackheads that usually start in adolescence. Over-the-counter lotions with benzoyl peroxide can help relieve blackheads, although for severe acne a prescription may be needed.
Identification
Dark reddish bumps due to under-the-skin infections are called boils. Boils are painful and can appear as one bump or in groups called carbuncles. Family Doctor.org recommends compressing a boil with a warm cloth and the use of an antibiotic ointment for severe cases. Notify your doctor if the bumps spread or don't drain after treatment. Boils that form around your hair follicles will likely heal on their own.
Prevention/Solution
A dark bump is often a harmless mole, although any mole that changes size and shape, bleeds easily and does not heal may be a sign of melanoma -- a type of skin cancer that spreads quickly and can be fatal. Your risk for melanoma is highest if you have fair skin that burns easily, red or blond hair and are over 50, says the American Academy of Dermatology. Alert your doctor immediately if you think you may have melanoma, as early detection increases your chance of survival.
Considerations
Treat any dark bumps or rashes on your skin caused by trauma with ice, compression, elevation and plenty of rest, says MedlinePlus. Your doctor may schedule a biopsy if he suspects cancer as the cause of your dark bumps, while an antibiotic is often the remedy for mild infections. Help your doctor determine the cause of your skin concern by coming to your visit prepared. Tell your doctor when you first noticed the dark bump and what symptoms you experienced, as well as if there is more than one bump on your body.
Warning
Call your doctor as soon as possible if you notice swelling or bumps of any color that cause pain and appear within one to two days, as you may have an infection or injury that requires prompt treatment.
