Bumps on Skin Symptoms
Symptom Checker: Symptoms & Signs Index
People often describe localized swollen areas on, or
under, the skin as lumps or bumps. While bumps on, or under, the skin may result
from conditions that give rise to a skin rash, many other conditions can result in solitary raised
lumps on the skin. Infections, tumors, and the body's response to trauma or
injury can all lead to lumps or bumps that appear to be located on or underneath
the skin.
Depending upon the cause of skin lumps or bumps, they may vary in size and be
firm or soft to the touch. The overlying skin may be reddened or ulcerated. Skin
bumps may or may not be painful or tender, depending upon the cause of the
lesions.
