Allergy
Direct exposure to an allergen may activate the immune system and lead to blisters on the feet. This condition is also known as allergic contact dermatitis. Common triggers include certain forms of metal, latex, or poison ivy. To reduce the risk of an allergic response, the most effective way is to avoid allergens. However, it is not always possible, especially when you have to face these triggers in the working or living environments. Topical steroids are typically the main treatment option to help ease itching and inflammation. In more severe cases, steroids need to be taken orally. [3]
