Anyone who has ever gotten a blister can testify that they are a pesky thing you’d rather not have. These small sacs of fluid that appear on the skin that can show up for a number of reasons. Usually, you can owe it to skin trauma, illness, and frequent irritation. Each type of blister requires a different method of prevention and care. Once you know how to deal with the blister you have, you can manage the pain more effectively and help speed up recovery. To learn more, keep reading to find out about some of the most common reasons that a blister can appear.

Friction from exercise

Exercising is an excellent way to improve your health, stamina, overall mood, and quality of life. Simply moving your body and getting more active can be just what you need to get out of a slump. However, repetitive activity can cause your clothes to rub against your skin, leading to the appearance of a raw, fluid-filled blister. If you try to ignore it and continue with your activities, it can cause further irritation and even lead to bleeding and an infection. The most common area that exercise blisters appear is on the foot. You can easily prevent foot blisters by using anti-chafing body balm, wearing better fitted running shoes, and protective running socks that keep our feet dry. If you like to wear running belts, choose one made out of a lightweight material like neoprene that has great grip and minimal bounce. All you need to do to help them disappear is to pop a cushioned band-aid on as soon as it forms, then let them get lots of air afterwards to heal on their own.

Second-degree burns

Burns can be categorised into 3 levels of damage. First-degree burns are simply cosmetic. They make your skin look like you were out in the sun for too long. Second-degree burns are partial-thickness heat damage that turns your skin red and causes blisters to form. Third-degree burns are the most extreme. They are full-thickness heat damage to the skin that makes it turn black or white. If you get a blister from a second-degree burn, try not to pick at it or break the skin as it can lead to an infection. Keep the area clean using fragrance-free soap and apply a salve like petroleum jelly or aloe vera to relieve discomfort. Wrap it with a sterile gauze, preferably non-stick types that will not adhere to the burnt area.

Chicken Pox

The Varicella-Zoster Virus (VZV) causes the viral infection commonly known as chickenpox. With it, you feel fatigued, feverish, dizzy, and develop tiny, itchy blisters all over. This infection is airborne so it’s important for anyone with chickenpox to isolate themselves until they feel better. Well it may be tempting, do not scratch the blisters as they will leave scars behind. Simply get lots of rest and have lukewarm baths for a speedy recovery.


Shingles are also an infection caused by the Varicella-Zoster virus (VZV). Symptoms may begin with you feeling pain and a burning sensation on your skin before small red bumps show up. These bumps then turn into a linear formation of painful red blister rash. 

If you think you are at risk of getting shingles, consult a medical professional and they might give you anti-viral medication to treat shingles. These medications work best if you start taking them in the first 48 hours of getting shingles symptoms. Put cool, damp cloths on the affected areas to relieve the itching and make sure not to scratch. 


The Herpes Simplex virus (HSV) can be either oral (HSV1) or genital (HSV2). HSV1 shows up as cold sores around the mouth, while HSV2 appear as painful scabs and ulcers in the affected area. However, due to the prevalence of oral sex, either type of herpes can appear on the mouth and genital are. They can be tricky to tell apart so consult the medical professional if you have any symptoms. They will take a sample of the fluid from the blister to more accurately decide what infection you have. They might prescribe antiviral medication to help the infection go away more quickly. Getting your period, feeling overtired or stressed, and illness can cause a flare up of the virus. Be sure to practice good oral hygiene and use protection during sex to avoid getting herpes. 


This highly infectious skin condition is common amongst young children. Bullous impetigo is less infectious and shows up as big but painless blisters. 

Non-bullous impetigo is more contagious and causes sores that easily burst to form a crust. You don’t usually need to do anything to help impetigo go away, but your doctor might recommend an antibiotic cream to stop it from spreading. 

Dyshidrosis Eczema

This type of eczema causes very small and very itchy blisters to form on your hands, feet, fingers, and toes. It is also known as pompholyx, foot-and-hand, palmoplantar, and vesicular eczema. Women are more prone to having this skin condition than men. Exposure to metals, stress, wetness, and seasonal allergies can usually trigger a bout of dyshidrosis eczema. Luckily, there are easy ways to keep this condition in check. Use a mild cleanser, a heavy ceramide dream to repair your skin’s barrier, try to manage your stress levels, and moisturise dry hands after washing them. If you are likely to scratch your body, keep your fingernails short to prevent breaking through the skin. 

With all this said, always consult a medical professional if you feel unwell and take precautionary steps to reduce the risk of developing blisters. And while you’re waiting to get medical advice, a little bit of rest and at-home care will help you manage any symptoms and feel better very soon.
