You really should see your gyn, they are trained professionals and can help you in diagnosing what it is. Any kind of lump should really be checked thoroughly.
Bartholin's glands secrete mucus that helps moisten the labia and help to lubricate the vagina. They can sometimes get infected and form an abscess, when that happens it is painful.
No, I don't think it is a tumour.
If it does start to hurt, that would indicate a possible infection which may have to be treated with an antibiotic.
The way to bring it to the surface is to heat up a spoon to and place that against the cyst. I don't know if this would work as I have never tried it.
It could be a swollen Bartholin's gland, which is usually not a problem but now and then one can get infected. Just have your gynecologist check it at your yearly exam.
Okay thankyou!! So you don't think it is a tumour ? Could it be a swollen lymph node or do they not exist in that region right in the vagina area
It is very likely to be a sebaceous cyst. Sometimes they do go on their own. If it does start to hurt and bother you, the doctor can arrange to have it removed.
