So about a month ago a bump appeared on the inside of my bottom lip after. A week or two later it disappeared and now it's back again. Only this time the bump is white kind of like it's filled with pus but before it was just a regular bump that was the same color as the inside of my lip. I'm very scared and worried that it might be herpes. Anyone who knows about this kind of stuff please help.

Sounds suspicious to me. You need to get a test to be sure though. Would not rule out some kind of mouth sore caused by your stomach. Whenever I would get something like that I would buy an over the counter remedy called Pepsin. You ask your pharmacist for this. It's a liquid that you take a spponful at a time to aid in digestion. A lot of times I would get these sores on my gums and the pepsin would help cure the sores.
