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.

    I have a very small bump on labia after I wore tight clothing. Was not painful or itchy, maybe a little tender when you press down very hard. Not tender anymore. It was tender for barely a day. Today I popped it and blood came out. no pain. bump has decreased a lot. almost flat now. i dont know what it is.

    Hi have what looks like a blood blister on the inner lip for several years now. I’ve had it looked at and my doctor said it was a blood mole? Lately it has gotten a little bigger and it popped. Now it will not stop bleeding. I’ve been tested and I’m clean so I am very confused on what this is.

  7. Sarah

    Hi, I’ve been having excessive discharge the past 7 months and it tends to be yellowish color when seen on the panty liner. I was wondering what would that be? Bacterial vaginosis?
    Also, i was going to have my “first time” with my boyfriend, but as he was trying to penetrate, there was a sharp pain down there. Could that be related to the discharge? Because I’ve been seeing redness inside the entrance of my vagina. Thank you

      It’s an infection in your vaginal tract. Needs to be checked up. Appropriate antibiotics are required.

      Are you sexually active? Let us know for diagnosis.

      Avoid washing the area with any soap or gel. Just clean it gently with water and start applying any emollient over it. This is to avoid dryness there.

  9. Elizabeth Jones

    I get these blood blisters on and around vaginal lips if you lightly squeeze it dark red blood comes out. I am not sexually active what could it be?

        1. Buddy M.D. Post author

          Likely to be blood filled pimples/ clogged glands. Just keep the area clean and dry. Wear loose lowers to avoid friction over them.

          Over the painful ones, you may start applying an antibiotic ointment thrice a day, like mupirocin/ bacitracin.

    Hello Doctor,

    I am a 22 yr old virgin girl. I have notice a bump on the side of the labia majora, it is almost near the panty line. I notice it 2 days back, it is quite painful. But today, I saw a tiny dot of blood from the bump. What should I do? Do i have to press it and try to drain it? or should i simply clean/wipe with some betadin srub. I am quite worried.

    1. Buddy M.D. Post author

      Try warm compress over it twice dialy. This may soften the bump and help in drainage over a few days. You need to be gentle, do not force drainage.

      Also, you need to start applying an antibiotic cream over it thrice daily. Mupirocin/ bacitracin may be used.

    I have these vaginal bumps that start of small then grow in size with blood inside of it. It’s on my outer vaginal lips and it won’t go away.

  12. Steph

    I’m sexually active and got tested before and after I had been with my new partner. We had a lot of sex over 4 days. 2 days after he left I noticed a really really small blood blister looking like bump on the inner lip of my vagina. No pain at all or any other syptoms. Im really worried what it could be.. it’s a red purple tent and not really even raised.

    1. Buddy M.D. Post author

      If it’s a single lesion, it’s unlikely to be an infection. May be a clogged gland. You may leave it such as. Likely to regress on its own.

      However, if it increases in size, becomes painful or multiplies in number, do let us know.

    I have a rather large dark red lump down below the sides directly on the entrance to my vagina. It is tender and somewhat sore. I have not been sexually active for 6 years.

      Could be an infected gland, that has got swollen. Need to see a gyne at the earliest. May require antibiotic treatment.
