Herpes is outside your mouth and not inside. When you have sores or bumps inside your mouth, they are canker sores which are different than a herpes simplex 1 lesion. Herpes simplex 1 is very common and the statistic is something like 80% of the population has it. What is the sign of it is the fever blister thing on the lip. You see that . . . don't make out with that person! So, you should move on from the herpes fear at this time. If you find yourself worried a lot about things, tell your mom. You may have anxiety that can get worse and will spill over to other stuff.
