Why do my feet keep getting blisters?

A blister: What is it exactly?

A blister is an under-the-skin-formed bubble filled with transparent, watery fluid (referred to as serum). Blisters develop at points of contact, such as where the foot comes into touch with a sock or with an ill-fitting shoe.

A contact point is where there is constant pressure, friction, and shear that is too high to keep the skin's integrity, allowing serum to leak in from surrounding tissue. The body's natural response to damaged skin is serum buildup, which serves to protect and cushion the skin below.

The following are the top three blister types:

  • Friction blisters are developed when the skin is constantly rubbed and chafed (often by poor-fitting shoes). These blisters are the most typical kind.
  • Burns, sunburns, and when the skin heats up after frostbite can all lead to heat blisters.
  • Blood blisters are brought on by pinching the skin. Broken blood arteries cause blood to flood the area instead of serum.

Why does a blister occur?

Typically, socks, shoes, or both are at blame when they brush against the skin. Blisters can develop from anything that causes constant rubbing, including:

  • A quicker speed while running or walking
  • Ill-fitting footwear anomalies (bunions, heel spurs, and hammertoes)
  • Due to heat and moisture, edema

How do I avoid blisters on my feet?

Of course, avoiding blisters altogether is the best course of action. Reduce pressure, friction, and shear forces on the foot to avoid developing blisters. Knowing how to prevent blisters makes the process very simple.


Buy the proper footwear

Blisters can develop during the first few wears of a new pair of shoes until they are broken in. Long walks or runs in new shoes might generate friction in new and unusual places.

Make careful you get your shoes fitted properly. The toes shouldn't chafe against the front of the shoe, and the heel shouldn't slide in properly suited shoes. When breaking in new shoes, go slowly and only cover short distances while running or walking. It's advisable to gradually increase mileage and speed while you break in your new shoes, even if they are the same brand and model as your old ones. In order to prevent the development of blisters and pain in the legs and feet, experts recommend wearing DrLuigi medical footwear. Soft and comfortable medical footwear relieves pain and provides enough space for your feet.


Pick appropriate socks.

Your foot and shoe are connected by your socks. Socks should fit comfortably and not be overly bulky. This prevents the socks from creasing, which could result in rubbing and blisters. Another technique used by hikers to avoid friction is to wear two pairs of socks.

Your socks' composition is also crucial. Socks made of synthetic materials and designed to wick away moisture encourage evaporation by enabling moisture to pass through the fabric without being absorbed. Contrary to conventional cotton socks, these wick away moisture from the skin's surface, keeping the feet dry and preventing skin deterioration.


Defend weakened areas

Blisters can be avoided by padding, taping, and treating hot regions that are prone to them. Prominences caused by bunions, hammertoes, and heel and bone spurs are typical locations. Blister formation can be considerably decreased by covering these areas with moleskin, which is a soft, resilient, woven cloth that is backed with glue, or an adhesive bandage similar to a band-aid.

Some patients additionally attempt to dust their shoes or feet with talcum powder, baby powder, antiperspirants, or petroleum jelly (Vaseline). Your results may vary when using lubricants to lessen friction and/or powders to absorb moisture to protect your foot from blister development.

How do I treat foot blisters?

It is still possible for a blister to form despite all precautions taken to lessen discomfort and friction. What's next?

In the case of small, painless blisters, we advise against puncturing or tearing the blister's roof. Use a non-adherent bandage to enclose the injured region, and then cushion it. It's critical to keep an eye on the blister for any swelling or leakage.

It's crucial to follow the right first-aid procedures to keep the region clean and lower the risk of infection if the blister's roof is ripped or punctured:

Rub alcohol or soap and water can be used to clean the blister.

Put on some antiseptic.

The area should be padded and covered with a non-adherent bandage.

Most blisters heal without complications or infection with the right care.

It's crucial to keep an eye out for any infection-related symptoms, such as swelling, redness, warmth, temperature, increased pain or drainage, yellow or darkish fluid, and bad odor. These could be symptoms of a deeper infection. Get medical help right away to stop the illness from getting worse or spreading.

People who are immunocompromised, have vascular disease, diabetes, neuropathy, or any other medical issues ought to consult a doctor right away. These people are more likely to experience infections and problems.
