According to the Mayo Clinic and Wikipedia, burning feet syndrome is a medical condition characterized by a sensation of burning, aching or tingling in the feet. The intensity of these symptoms ranges from mild to severe and, in rare cases, it can also interfere with sleep. It is more common in women than in men, and it usually appears in patients between the ages of 20 and 40.
The Mayo Clinic further mentions that persistent symptoms of burning feet syndrome are usually caused by peripheral nerve damage, which may arise due to chronic alcoholism, exposure to poisons, chemotherapy, HIV infection, or medical conditions such as diabetes, Charcot-Marie-Tooth disease, chronic kidney disease, hypothyroidism, deficiency of certain B vitamins, or tarsal tunnel syndrome. It may also be a result of complex regional pain syndrome, a medical condition that involves chronic pain due to problems in the functioning of the nervous system.
Burning feet syndrome is also known as Grierson-Gopalan syndrome, according to Wikipedia. It usually manifests in the soles of the feet. However, in some patients, the burning sensation can also extend to the ankles and the lower legs. The symptoms are usually stronger during the night and may subside in the morning. Patients who suffer from psychosomatic disorders may also exhibit psychological symptoms along with the symptoms of burning feet syndrome.
