We hadve all at one stage experienced a blister in one form or another and creates great discomfort which can the lead on to other issues due to the person walking awkwardly trying to relive the pain.


What actually is a blister?

A blister is a small pocket of serum, blood or pus depending on the cause and weather it becomes infected. This fluid acts as a cushion to the skin underneath that may have been damaged or irritated giving the skin a chance to repair itself. Blisters are able to develop anywhere on the skin but most commonly on hands and feet.

What causes blisters?

Blisters are most commonly caused by friction or heat resulting in the skin becoming damaged and needing to heal itself.

In terms of friction any rubbing has the potential to cause one weather that be by poor fitting shoes or holding equipment in your hands. Sports people are particularly susceptible due to to sweat making the skin surfaces moist which increases the chance of a blister developing. Warm conditions causes by exercise is also believed to be a contributing factor. A active person may also be wearing shoes more often then someone who doesn’t do as much sport again increasing the likelihood. Although sportspeople are more likely to have blisters this doesn’t mean that people who don’t exercise will be free from blisters in this way.

Exposure to excessive heat though sunburn or flames and even steam is a common cause due to the damage that the heat causes to the top layers of skin. It is also possible that other forms of radiation could contribute namely blisters by UV rays which can indicate skin cancer.

Other causes include

  • medical conditions (chickenpox)
  • contact with chemicals (detergent)
  • Infection
  • allergic reactions
  • cold


In most cases a blister should be left to heal naturally without bursting it or peeling off the skin. This will just lead to to an increased haling process as well as the chance of it becoming infected. A normal blister shouldn’t need any medical attention only if it is particularly painful or if it is belied to be infected should a person contact the GP. This is also the cause should the blister be in an usual place or should it be caused by an allergic reaction.



To prevent a blister from forming it is vital to have the the correct footwear to avoid rubbing as much as possible. Wearing suitable socks is also an effective method of combating this due to moisture being absorbed as well as providing a cushion. When handling tools wear gloves to stop the friction causing blisters. In terms of heat and chemicals make sure your skin is not exposed with the correct safety procedures and equipment in place.
