When are mouth ulcers considered as herpes? i have a huge ulcer on my bottom lip. can it be caused by stress?

Chocolate ; Nuts: Mouth ulcers are one form of herpes, not the genital kind. Stress weakens the immune system which holds herpes in place so we don't have outbreaks. Lysine is a natural supplement you can take to help. When it is lowered by things like nuts and choclolate (which contain arginine) and stress outbreaks are more common. The very best to you.

Yes/No: Oral herpes is caused by hsv (virus). Once you are infected, the virus stays in your nervous system and affect your body at times of stress. Without the hsv, stress only will not cause cold sores. Ulcers by herpes (hsv) are called cold sores, and share recognizable characteristics in their size, locations, etc. Culture or blood test can be done to confirm this viral infection.
