Hell.

Thanks for posting your query.

I have gone through the picture provided by you. Most probably, you are suffering from recurrent Apthous ulcer which appears after stress.

These ulcers disappear with good oral hygeine and vitamins.

Only syphilis in its primary stage can produce ulcer through oral contact if your partner has a genital ulcer. Chancroid produces multiple ulcers associated with regional painful lymphadenopathy. Hence you need not worry about these two infections.

If the lesion is due to viral infection. It may also resolve within a week.

So I suggest:
1. Good mouth wash with hexidine.
2. Topical application with kenacort in oral paste.
3. Supportive vitamins.

I hope, this helps to answer your query. Please accept my answer in case you have no follow up queries.

Regards.
