[34M] Concern about a transient lip bump with subsequent hyperpigmentation

What might be happening

Based on your symptoms, here are a few possible conditions:

• Mucous Cyst: These are small, fluid-filled sacs that form on the lips or mouth. They are often caused by lip biting, lip sucking, or other minor trauma. They are typically painless unless they rupture and can leave a scar after healing.

• Fordyce Spots: These are small, painless, raised, pale or white spots or bumps 1 to 3 mm in diameter that may appear on the lips. They are not associated with any disease or illness and are a natural occurrence on the body.

• Cold Sore: These are small, painful, fluid-filled blisters that usually occur on or around the lips. However, you mentioned that the bump was painless and there was no fluid, which makes this less likely.

• Actinic Keratosis: This is a rough, scaly patch on your skin that develops from years of exposure to the sun. It's most commonly found on your face, lips, ears, back of your hands, forearms, scalp or neck.

Please note that these are only possibilities and not a definitive diagnosis. It's important to consult with a healthcare provider for an accurate diagnosis.

What you can do

1. Keep the area clean and avoid picking at or popping the bump.
2. Apply a lip balm or cream to help with the dryness. Look for one that contains SPF to protect your lips from the sun.
3. If the bump does not resolve on its own in a few weeks, or if you notice any changes such as an increase in size, changes in color, or if it becomes painful, you should consult with a healthcare provider.

What you should look out for

• Any changes in the size, color, or shape of the bump
• Development of new bumps
• Pain, itching, or burning
• Signs of infection such as redness, swelling, or pus
