Why has crack on bottom of big toe turned into a huge blister?

A crack on the bottom of the big toe that turns into a huge blister is typically caused by a condition known as dyshidrotic eczema. Dyshidrotic eczema is a type of eczema that is characterized by small, itchy blisters on the palms of the hands and soles of the feet. However, in some cases, the blisters can also occur on other areas of the body, including the big toe.

There are several possible causes of dyshidrotic eczema, including:

* Genetics: Dyshidrotic eczema is thought to be linked to a genetic predisposition, and it often runs in families.

* Allergens and irritants: Certain allergens and irritants, such as nickel, rubber, and certain chemicals, can trigger dyshidrotic eczema in susceptible individuals.

* Stress: Stress can also be a trigger for dyshidrotic eczema.

Treatment for dyshidrotic eczema typically involves avoiding triggers, applying topical corticosteroids, and using moisturizers. In some cases, oral medications may also be necessary.

If you are experiencing a crack on the bottom of your big toe that has turned into a huge blister, it is important to see a doctor to get a proper diagnosis and treatment plan.
