In the middle of my upper lip there is a bump that is a different colour from the rest of my lip and is a pink colour. I’m pretty sure it isn’t a pimple or anything like that as I’ve had it for most of my life (I may be talking about my tubercle) although unlike many others this bump stands out from the rest of my lips
If you have had it most of your life, it likely isn't anything that will cause you harm. If it's bothersome though, you might see a doctor about getting it removed.
