Causes of Blisters on Toes and What to Do About Them

A Guide to Understanding Blisters on the Toes

Types of Blisters on Toes

There are three broad categories of blisters, which differ by the fluids that fill them. These characteristics can point a healthcare provider in the direction of the underlying cause.

• Vesicles: These are clear blisters filled with serum, a clear fluid that makes up the clear part of blood. Most common blisters involve serum.
• Blood blisters: These are typically caused by trauma. They can occur when something pinches but does not break the skin. Instead of serum, blood pools and forms a pocket under the skin.
• Pustules: These are pus-filled pockets that develop due to infection. With a skin infection, dead white blood cells, dead tissues, and dead bacteria or fungi can pool into a liquid called pus.

Causes

There are various causes of blisters, some of which are harmless and clear on their own. Others may be signs of underlying disease requiring specialist medical care.

Friction

Friction blisters are the most common type of blister on the toes. They can develop when a person is on their feet for a long period and their toes continuously rub against their shoes or socks.

Moisture

Excessive foot moisture can cause maceration, the softening and breaking down of skin due to the accumulation of sweat or water. When this happens, fluids can seep beneath breaks in the skin and form a large vesicle.

Burns

Blisters form in response to a second-degree burn. With second-degree burns, blistering is a way to protect underlying tissues from damage. Causes include fire, steam, certain chemicals, and contact with any object or surface heated to over 131 F.

Severe Frostbite

If your toes are exposed to extreme cold for a long period, blisters may also appear. Typically, the toes become frostbitten before tiny vesicles form, merging into a larger one. Pain, burning, tingling, and a waxy skin appearance are also common.

Allergies

Different allergic reactions can cause blisters. These occur when an allergen (allergy-causing substance) causes immune cells in the skin, known as mast cells, to break open and release a chemical called histamine into surrounding tissues.

Conclusion

Blisters on the toes can be caused by a variety of factors, including friction, moisture, burns, and allergies. Understanding the underlying cause of a blister is essential for proper treatment and prevention of further complications.
