Crusty bumps on the skin can be unsightly, itchy and uncomfortable. While usually not a sign of a serious medical condition, these bumps can make you feel self-conscious about your appearance and may be a sign of an underlying health issue. Seek treatment for your crusty bumps if they don't respond to over-the-counter treatments after six to eight weeks.
Identification
Crusty bumps and lesions can appear at any point on the body, says the American Academy of Dermatology. Often referred to as cysts, these lesions occur when a hair follicle gets clogged with oil, dead skin cells and bacteria. Often, these bumps are treated using corticosteroid shots or antibiotics. However, this can cause the bumps to dry out and scab over, leaving a crusty appearance.
Allergies
An allergic reaction may be to blame for your crusty bumps. These are often referred to as hives and can occur when your body is exposed to something it's sensitive to. Common culprits include peanuts, gluten or lactose. A shower with cool water can help ease the itching and irritation of the bumps. A series of tests with an allergist can help determine the source of your allergy and allow you to avoid exposure to the irritant.
Bug Bites
The sudden development of a single or small cluster of crusty bumps on the skin may be the result of a bug bite or sting. In fact, if you're allergic to the venom in the bite, your skin might break out or scab, especially if you scratch at the lesions. If you exhibit signs of a severe allergic reaction to the bite or sting such as nausea, vomiting, dizziness, swelling or problems breathing, go to the emergency room immediately.
Cleansing
Washing your skin every day can help remove oils and dirt, which may be the cause of your crusty bumps. Use a mild cleanser so as to not overly dry your skin, says the American Academy of Dermatology. This can make the bumps itchier. Using an oil-free moisturizer should also help soothe irritation and keep your skin hydrated.
Medical Help
In some cases, crusty bumps could be a sign of a more serious condition, such as skin cancer. If the bump is strangely colored, grows in size or doesn't go away within a few weeks, consult a dermatologist for an accurate diagnosis and treatment plan.
