Blood Blister on Vagina

Blisters and pimples on the genitals are common.

A blood blister is usually due to some infection, it may be herpes or any other STD. So, they require examination by a doctor.

Causes of Blisters Beside Herpes

In girls who are not sexually active, a clogged sebaceous gland (or a pimple) may get filled with blood to form a blister.

This may occur due to:

  • Friction, from clothes or movements
  • Improper clothing
  • Stress or poor nutrition
  • Poor hygiene


  • Firstly, wear loose clothing down there. Let your under clothing be of cotton fabric.
  • Avoid friction over the blister as far as possible.
  • Keep the area clean and dry. Clean it twice a day with plain water, no soaps.
  • Blisters usually subside on their own with time. If they become painful, apply mupirocin ointment over them.

  3. Kate

    I noticed a red blood blister on the inside lip of my vagina and it was kind of itchy and a little bit painful. After two days I noticed the middle started getting white, and now the whole thing is white and it is not pus. Is it infected? And it hurts pretty bad now. Especially to pee.

      Yes, this one appears infected. Try warm compress over it. This may help draining it. However, be gentle, do not force drainage.

      You may start using a topical antibiotic cream over it. Mupirocin/ bacitracin etc. may be used.
