Red blotches on the bottom of feet can be alarming. However, in most cases, red blotches aren't serious. Common causes of this skin issue are athlete's foot and contact dermatitis. Once you determine which condition is responsible for your red blotches, treatment will provide relief. You can take steps to prevent future outbreaks and discomfort.
Causes
A grouping of any of three types of fungi collectively called dermatophytes can cause athlete's foot infections. The fungus is present on normal skin. However, an infection occurs when the fungus starts growing out of control. Damp and close environments promote athlete's foot. Contact with infected surfaces and objects spreads this infection.
Contact dermatitis is another infection that causes red blotches on the bottom of the feet. Use of strong soaps, detergents or an allergic reaction to socks and shoes cause this condition.
Treatments
Use topical medications that contain the ingredients butenafine, clotrimazole or miconazole to treat athlete's foot infections. These medications are available over the counter. Treat infections that don't respond to over-the-counter methods with clotrimazole and miconazole, recommends MayoClinic.com. Oral prescription medications, such as itraconazole and fluconazole are another treatment option.
Use hydrocortisone creams to treat contact dermatitis, recommends MayoClinic.com. Use of an antihistamine, also available over the counter, is another treatment option. Application of a dressing after applying topical creams allows the medication to work more effectively.
Considerations
Take a cool oatmeal bath if red blotches are itchy. Uncooked oatmeal soothes irritated skin, according to MayoClinic.com. Sprinkling a little baking soda into water also helps. Avoid scratching the feet if possible. This makes the skin issue worse and increases the risk of cracking skin. Skin that is cracked is at higher risk for infection.
Prevention
Prevent athlete's foot by keeping feet dry. Choose socks and shoes made of natural materials, such as cotton. Don't allow damp socks to sit on the skin for long. Change socks quickly and wear well ventilated shoes. Protect the feet in public areas, such as locker rooms and pools. Wearing a pair of sandals minimizes the risk of infection.
Avoid contact dermatitis breakouts by avoiding the irritant. Applying a barrier cream, such as a heavy moisturizer, also assists in avoiding allergic reaction. Select products and detergents that are free of fragrance and irritants.
Warnings
If red blotches on the feet don't improve after two weeks of over-the-counter treatment, contact your doctor. He can examine the feet and make a diagnosis. Based on the diagnosis he will recommend the appropriate treatment option. Some outbreaks require prescription treatments to heal.
