[Tatyana]

The dear Doctor! Prompt, please, that with me. About 5 years in the top part of greater or big sexual labiums (basically at the left) before, during or after a menses appears single, morbid on oshchup a nodule. The size - about a match head, sometimes about a pea, is marked or celebrated reddening. But for 3 4 days completely and completely resolves. Happens not every month. It can herpes? At me no other signs are present. In advance thanks!

This status is connected with a status of vestibular glands (they happen different - greater or big and small) vaginas and wears the name vestibulit (Vestibulitis) or vulvovestibulit. It is a lot of reasons of occurrence, if communication or connection with menses - probably any hormonal disturbances is observed.
