Go to the doctor immediately when you have sores and get them cultured for herpes and herpes type. Tiny red bumps on the tip of your tongue may be inflamed taste buds.
This could be a reaction to a toothpaste, mouthwash, food - anything you are putting in your mouth.
Herpes sores aren't typically on the inside of your mouth - maybe just inside the lips, but after your first outbreak, they aren't typically inside.
