Blisters are usually caused by friction on the skin, causing fluid to build up underneath the skin where it was rubbed. Many doctors recommend that you don’t pop a blister if you want to prevent scarring and infection and will advise you to burst a blister, but if you really want to burst it, follow these steps to make sure: safe.
Steps
Check before bursting blisters
- Where is the blister? It is safer to break a blister on a foot than to break a cold sore on the lips or inside the mouth. Herpes sores and blisters inside the mouth should be checked by a doctor.
- Is the blister infected? If there’s a yellow discharge, it’s infected and you should see your doctor. [3] X Trusted Source National Health Service (UK) Go to Source
- Does the blister interfere with daily life, such as making it difficult to walk? If so, now is the time to safely break it.
- Second-degree burns that cause blisters should be treated gently with a prescription burn cream. You should see your doctor to get the right prescription and to know how to care for a sunburn blister. [5] X Research Sources
- Bloody blisters are a sign of a deep wound. It can heal on its own but many people mistake it for melanoma (pigmentation). Therefore, if you are not sure, see your doctor to check.
Prepare to burst the blister
- Use regular unscented soap to wash your hands. This prevents any irritation from the chemical and avoids the transmission of bacteria from the hands to the delicate skin after the blister has broken.
- Antiseptics such as betadine are available over the counter. However, you should be careful with betadine as it will stain your skin, clothing and other surfaces.
- Gently pour betadine or rubbing alcohol onto the blister and surrounding skin. If washing with soap and water, use unscented. Gently rub the affected area with your hands, but be careful not to press too hard so as not to break the blister, then rinse with water.
- If you choose to use a sewing needle at home, you will need to soak the needle in rubbing alcohol first.
- Do not heat the needle or blade over a fire, as it will become contaminated with carbon molecules that irritate the skin and increase the chance of infection. [10] X Research Source
Break the blister
- Do not pierce the blister with a needle to dry the water. This method increases the risk of infection.
- Do not press too hard or tear the blister to allow fluid to drain. This leads to the risk of injury to the skin underneath.
- Apply the ointment a few more times and change the dressing every day until the skin heals. This process usually takes about 1 week. [15] X Research Source
- The skin becomes inflamed as the area around the blister becomes increasingly red and swollen. Besides, the body temperature also increased higher than 37°C. If the area of the skin hurts more and is accompanied by the above symptoms, it is possible that the wound is infected.
- Pus is a yellow fluid that oozes from an infected wound. If the blister (which hasn’t burst or has burst) oozes pus, see your doctor to prevent the infection from getting worse.
- When paddling, wear watersport gloves or wrap tape around the paddle handle to reduce friction. [19] X Research Source
Warning
- Some blisters form due to a medical condition such as autoimmune bullous disease, or an infection such as bullous impetigo. If you have blisters that appear for no apparent reason, or multiple blisters that come back over and over again, you should see your doctor.
Advice
- Make sure everything (hands, needles, skin around the wound, blisters) is disinfected to prevent infection.
- You can see your doctor, dermatologist, or nurse to help drain the blisters with a sterile needle. This is especially important when dealing with large blisters. [20] X Research Source
