Lipomas aren’t usually painful, but they can be uncomfortable if they press against a nerve or develop near a joint. Many people who have a lipoma don’t notice any symptoms. Lipomas are usually: Encapsulated: They don’t spread to the tissues surrounding them. Painless: However, some lipomas cause pain and discomfort depending on their location, size and if blood vessels are present. Round or oval-shaped: The fatty lumps of rubbery tissue are usually symmetrical. Moveable: They sit just beneath the skin’s surface and move when you touch them. Smaller than 2 inches in diameter: In a few cases, lipomas can be larger than 6 inches wide.
