Itchy, burning feet may stem from a temporary condition that may easily resolve with a few changes to lifestyle and hygiene habits. On the other hand, burning feet may be an indication of a serious medical condition. Burning feet are more common in people over 50, according to ePodiatry. Generally, if a person has symptoms of itchy, burning feet and is otherwise in good health, the condition is usually not medically serious.
Gout
Gout causes inflammation of the joints. A common symptom of gout is a burning sensation that occurs on either side of the feet or the toes, particularly the big toe. Gout patients may awaken during the night with a burning sensation in the big toe. Some patients describe the burning sensation as the feeling that the big toe is on fire.
Blood Disorders
Erythromelalgia and thrombocytopenia are blood disorders that may cause symptoms of itchy, burning feet. Erythromelalgia is a rare circulatory disorder that causes symptoms of burning pain in the lower extremities, caused by the periodic blockage of blood flow in the blood vessels. Thrombocytopenia is a blood disorder that prevents the blood from clotting.
Neuropathy
Patients who suffer from nerve damage may experience burning feet. Diabetic patients may have nerve damage due to the high glucose levels in the blood. Typical symptoms of nerve damage include itching, tingling, numbness and burning in the extremities.
Vitamin Deficiencies
A deficiency in vitamins B6, B16 and thiamine could cause symptoms of burning feet and itchy skin. Vitamin deficiencies may be due to a poor diet, too much alcohol consumption, chronic diarrhea or heavy metal poisoning. Skin may itch due to dryness, and burning feet may stem from a lack of oxygen and nutrient-rich blood.
Metatarsalgia
Metatarsalgia is a foot disorder that causes sharp, aching or burning pain in the toes and ball of the foot. The condition stems from the overuse or degeneration of fat pads on the foot. According to the Foot Health Network, improper footwear used for high-impact activities can cause excessive pressure on the foot, leading to the condition of metatarsalgia.
Fungal Infection
A fungal infection is common among athletes and younger aged people. Fungal infections of the foot may develop from excessive perspiration, poor hygiene habits and lifestyle. Feet and footwear become breeding grounds for bacteria due to the dark, moist and warm environment where bacteria thrive. When a fungal infection develops on the foot, common symptoms are itchiness, stinging or burning. Wearing clean, breathable cotton socks -- especially when working out or playing sports -- may reduce the chances of getting a fungal infection of the foot.
