Hello,
From your symptoms,it looks like a Bartholin's abscess or cyst. There are glands in the vaginal lips
called Bartholin’s glands. These can become painful and swollen, and an abscess can form. This often causes
blockage in the main duct from the gland, and a cyst develops. This is felt as a painless, hard swelling.In
such cases, antibiotics may be helpful, or surgical treatment might be required.
Other possibilities are sebaceous cysts (accumulations of secretions that can occur anywhere on the skin or
mucosal surfaces), lipomas (fatty deposits) ,fibromas (fibrous tissue deposits) or viral warts(small raised
pimples to a mass of large, cauliflower-like growths. The virus that causes them is passed on during sex).
Cancer of the vulva is very uncommon and almost always occurs in elderly women.So pls don’t worry about it.
An examination by a gynecologist will be the best as it is only after an examination that it will become clear
what the swellings that you have noticed are due to.
Hope it helps.Take care and pls do keep us posted if you have any additional queries.
