What are skin bumps?
Skin bumps refer to any type of swollen area or lump on the skin that can occur with or without itching. The bump may be smooth or rough, hard or soft, and light or dark colored. You may have a single skin bump or several raised areas over any part of the body.
Many different diseases, disorders and conditions can lead to a bump or raised surface on the skin. Infections, injuries, growths (benign and cancerous), and inflammation can all lead to lumps or bumps on or underneath the skin. Skin bumps may be localized to a specific area of your body, or they may cover a large area of your body.
The appearance, color and location of skin bumps can vary widely. Here are some examples of different bump characteristics that you can discuss with your doctor:
Bump around the base of a hair follicle
Bump or raised spot with an irregular border or color that has grown over time
Bump that is painful to touch
Itchy bump or raised rash
Raised rash that spreads over large areas of the body
Scabbing or crusty bump
Small, pus-filled bump
Particularly important is whether you have additional symptoms that accompany the skin bumps, no matter how trivial you think they may be.
If your skin bumps are persistent or cause you concern, contact a medical professional. In particular, if you develop hives (raised bumps or welts), facial or tongue swelling, and difficulty breathing after taking medicine or eating certain foods, seek immediate medical care (call 911).These symptoms may indicate an allergic reaction that can be a life-threatening medical emergency.
What other symptoms might occur with skin bumps?
Skin bumps may occur with other symptoms, depending on the underlying disease, disorder or condition. These symptoms can either occur locally at the site of the bump or involve other body systems.
