What is what does it mean when you get a bump on your lip?

A bump on your lip can be caused by a variety of factors, ranging from harmless to requiring medical attention. Here's a breakdown of common causes:

  • Cold Sores: Also known as fever blisters, these are caused by the herpes simplex virus (HSV-1). They typically start as small blisters that can itch, tingle, or burn before breaking open and crusting over.

  • Canker Sores: These are small, painful ulcers that appear inside the mouth or on the lips. Their exact cause is unknown, but they can be triggered by stress, certain foods, or minor injuries. Canker sores are not contagious.

  • Fordyce Spots: These are small, painless, pale or white spots that are often found around the lips or inside the cheeks. They are enlarged oil glands and are completely harmless.

  • Mucocele: This is a fluid-filled cyst that develops when a salivary gland duct becomes blocked. They often appear on the inside of the lower lip.

  • Allergic Reactions: Contact with allergens like certain lipsticks, foods, or medications can cause lip swelling and bumps.

  • Bacterial Infections: Less commonly, a bacterial infection can cause a bump on the lip. This usually involves redness, pain, and pus.

  • Oral Cancer: While less likely, a persistent lump or sore on the lip that doesn't heal within a few weeks should be evaluated by a doctor to rule out oral cancer.

It's important to monitor the bump and consult a doctor if it:

  • Is very painful.
  • Doesn't heal within a few weeks.
  • Is accompanied by other symptoms like fever, swollen lymph nodes, or difficulty swallowing.
  • Changes in size, shape, or color.
