What Could Cause Tiny Bumps on My Lips If They're Not Cold Sores?

There are a few things that might cause tiny bumps on your lips if they aren’t cold sores. One possibility is a lipoma, which is a small, benign (non-cancerous) growth made up of fat cells. Lipomas can occur in the mouth, including on the lips, and they usually grow slowly without causing pain. Another possibility is a reactive growth from irritation or minor injury, where your tissue may overgrow in response to repeated rubbing or pressure, forming a small bump. In some cases, tiny bumps can be an early sign of cellular changes in the lip lining. For example, in epithelial dysplasia, cells change slightly due to irritation; this is usually monitored by doctors to make sure it doesn’t develop into something more concerning over time. Most of these bumps are harmless, but it’s always a good idea to keep an eye on them. If you notice that the bumps begin growing, changing color, or feeling different, consider getting them checked by a doctor to ensure they are benign.
