How can I tell the difference between a pimple and coldsore?

This morning I found a bump on my lower lip and I thought it was a coldsore first. So, I used Abreva and thought it would get smaller/less red.


But then my friend said it might be a pimple.


How can I tell the difference between the two?|||coldsores hurt|||Cold sores are usually a cluster of small blisters, red, and itch. You usally get cold sores on the same spot on your lip over and over. So if it%26#039;s not where you usally get one, it dosen%26#039;t itch, and it%26#039;s a white head and not blisters it might be a pimple.|||Visit the skin care source below. It discusses cold sores and other lip problems and their treatment.|||cold sores are flat whereas pimples almost come to a point. also cold sores will be just off the lips. you can%26#039;t pop a cold sore like a pimple.
