What Can Cause Blisters on the Vagina Apart From Herpes?

Blisters, sores, ulcers, rashes and other irritation in the vaginal area can have many different causes. You really need a doctor to examine you and give you the correct diagnosis.

In terms of sexually transmitted infections, there are several possibilities:

  • Genital herpes may cause small blisters that burst and form painful, open sores on the genitals.
  • Genital warts, caused by HPV (human papilloma virus), appear as small, round lumps that are usually painless.
  • Syphilis can cause a small, painless sore that can look like a pimple, a flat, wet wart, or an open sore.
  • Cancroid can cause soft, painful sores on the genitals that bleed easily.
  • Molluscum contagiosum is a viral skin infection that causes raised, pearl-like papules or nodules that are usually painless.

Vaginal sores are not necessarily caused by a sexually transmitted infection. The skin may becomes red, sore, or inflamed after contact with perfumes, detergents, fabric softeners, feminine sprays, ointments, creams, douches. Some skin disorders involve scaly and itchy rashes.

Changes that may lead to cancer of the vulva may appear as white, red, or brown patches on the vulva, which may be itchy. A Bartholin's cyst is a soft lump just inside the opening of the vagina.
