Should You Pop A Blood Blister

Blood Blister: If you notice a raised piece of skin that has blood inside, it’s a blood blister. These blisters are not much different than ones that have clear fluid inside of them. For the most part, they are harmless and will go away within a few weeks without treatment.

Blisters are raised bubbles under the top layer of your skin that are filled with fluid. This fluid might be a clear liquid, blood, or pus. Regardless of what they’re filled with, blisters can be very uncomfortable, especially if they’re on a part of your body that you use a lot.

Should You Pop A Blood Blister

You’ve probably heard that it’s best to leave blisters alone. While this is true, it’s not always practical. Read on to learn how to tell when it might be time to take things into your own hands and how to do it safely.

Blood Blister On Finger

A blood blister can form anywhere on the body where the skin is pinched but does not break open. Closing a drawer on a finger or lifting heavy weights for prolonged periods can cause blood blisters.

Other causes may include:

  • a tool or other object repeatedly rubbing against the skin
  • poorly fitting shoes that pinch the skin
  • sweaty feet that cause extra friction
  • minor trauma from pinching the skin between two objects
  • severe frostbite

Blood blisters in the mouth are often related to another condition. If someone has a blood blister in their mouth, they should see a doctor. Some causes of blood blisters in the mouth include:

  • mouth cancer
  • nutritional deficiencies
  • excessive alcohol use
  • allergies
  • bleeding disorders

Risk factors

It is possible for nearly anyone to get a blood blister. Preventing blood blisters involves people taking good care of their health and body and using appropriate protection in situations that require it.

People should take the following steps to reduce the risk of developing a blood blister:

  • wear gloves when working with tools or lifting heavy weights
  • wear appropriately sized footwear
  • keep feet dry

When to see a doctor

Most blood blisters will heal on their own over the course of 1–2 weeks. People do not typically need to take any special actions to treat the blisters, except keeping the area with the blister clean.

Sometimes, a person may experience some extra problems, which may include the blister not clearing up on its own. Signs that a person may need to see a doctor include if:

  • the blister repeatedly returns
  • there is no apparent reason for the blister to have formed
  • the blister is caused by an allergic reaction
  • multiple unexplained blisters have formed
  • there are symptoms of infection, such as red lines or warmth spreading from the blister
  • blisters have formed in the mouth or eyelids
  • The blister is making it difficult for a person to move their hands or walk

Blood Blister Inside Cheek

Fever blisters, also called cold sores, are red blisters filled with fluid. They form on the face, usually near the mouth. They can also appear on the nose, inside the mouth, or on the fingers. A few fever blisters often form together as a clump.

Fever blisters are caused by the herpes simplex virus, which is easily spread to others through close contact. Never pop a fever blister. It won’t help it heal any faster and you run the risk of spreading the virus to other areas of your skin or to other people.

How do I safely pop a blister?

If you have a friction or blood blister in a frequently used area that has a high risk of rupturing on its own, it may be best to pop it yourself to make sure it’s properly protected against infection.

Just keep in mind that blisters usually heal on their own within a few days. Popping a blister disrupts this natural process, and it could mean that your blister will take a little longer to completely disappear. You’ll also need to keep a close eye on it after you pop it to monitor for signs of infection.

If you’re looking for a quick, easy fix, your best option is to just let the blister run its course. For added protection, you can apply moleskin to the blister.

But if you do need to pop a blister, follow these steps to minimize your risk of infection or other complications:

  1. Wash your hands and the blister. Wash your hands with soap and warm water. Clean the surface of the blister thoroughly with alcohol, iodine, or an antiseptic wash.
  2. Disinfect a needle with alcohol. Soak a needle for at least 20 seconds in rubbing alcohol to disinfect it.
  3. Carefully puncture the blister. Poke three or four shallow holes around the edge of the blister. You want to keep as much of the skin intact as possible. Allow the fluid to drain out.
  4. Cover the blister with ointment. Apply an ointment, such as petroleum jelly, to the blister.
  5. Apply a dressing. Cover the blister tightly with a bandage or gauze. You want the intact skin of the blister to press against the underlying skin.
  6. Repeat if necessary. Blisters tend to fill back up quickly. You may need to perform these steps every six to eight hours for the first 24 hours. After that, change the dressing and apply ointment daily.

Blood blisters should be left alone so they can heal. Blood blisters and friction blisters usually heal after one or two weeks. They heal because new skin forms below the blister’s raised layer. Over a period of days or weeks, the liquid in the blister will dry out.

Keep the blood blister protected as it heals. You may want to wrap it in a protective layer, such as a bandage. If the blister hurts, you can apply ice wrapped in a towel to it. You may find it helpful to take acetaminophen (Tylenol) or ibuprofen (Advil) to ease the pain.

You should not try to lance the blister, which is sometimes recommended for friction blisters without blood. The raised skin protects you from bacteria entering the blister. But contact your doctor if the pressure from the blood blister is painful and it needs to be drained.

What is the outlook for a blood blister?

Seeing a blister filled with blood is nothing to panic about. Blood blisters are fairly common and are generally caused by injury without the skin breaking or by friction. The best treatment for a blood blister is to let it heal on its own over a few weeks.

It’s important to determine what caused the blister. If your footwear is too tight, find shoes that fit you better. If the blood blister appeared after repetitive motion with a tool, consider protective gloves. If your feet are blistered from exercise, try wearing socks designed to wick sweat from your feet. This may reduce the friction between your foot and your shoe.

Blood Blister On Foot

Friction blisters are caused by repeated pressure or rubbing, which creates irritation. They can form from wearing shoes that don’t fit properly, especially if they’re too tight. While they can form in any area that’s exposed to friction, the hands and feet are common sites.

Once you remove the source of friction, the fluid usually drains on its own within a few days. You’ll then develop a new layer of skin under the blister. Once the skin has developed, the skin from the original blister will fall off.

If the blister continues to be exposed to friction, it can take several weeks to heal. In the meantime, the blister may pop on its own, oozing fluid. This also leaves the blister vulnerable to infection. If you have a friction blister that you can’t protect from irritation, such as one on the index finger of your dominant hand, you might want to consider safely popping it to avoid infection.

Blood Blister Treatment

Your GP might burst a large or painful blister using a sterilised needle. If your blister is infected, they may prescribe antibiotics.

They can also offer treatment and advice if blisters are caused by a medical condition.

Blisters develop to protect damaged skin and help it heal. They are mostly caused by friction, burns and skin reactions, such as an allergic reaction.

Blood blisters appear when blood vessels in the skin have also been damaged. They are often more painful than a regular blister.

If you regularly get friction blisters:

  • wear comfortable, well-fitting shoes
  • gradually break in new shoes
  • wear thicker wool socks during exercise
  • dust talcum powder in your socks if you get sweaty feet
  • wear protective gloves when you exercise or if you use tools at work
