Burning Sensation in the Feet: Causes, Symptoms, and Management Methods
What Is the Sensation of Burning Feet?
The sensation of burning feet may appear mildly in some individuals, while in others it can be more pronounced and disturbing. This condition is generally characterized by an increase in temperature and pain in the soles of the feet, but it can sometimes spread to the ankles and legs. The burning and pain may persist continuously or decrease and disappear periodically. Additionally, sensations such as tingling or numbness may also be observed in these areas.
What Is Burning Feet Syndrome?
Medically known as "Grierson-Gopalan syndrome," burning feet is a syndrome most commonly felt on the soles of the feet, but it can sometimes extend to the ankles and legs. This syndrome presents with a disturbing increase in heat, burning, and sometimes numbness and tingling in the feet. The severity of complaints varies from person to person, but in most cases, it becomes more pronounced at night and may negatively affect sleep quality.
The condition of developing excessive sensitivity to every touch on the feet is called "hyperesthesia" and is a common symptom in burning feet syndrome. Below is a list of common symptoms that may accompany this syndrome:
A sensation of increased heat or burning, especially at night
Numbness and tingling in the feet or legs
Sharp, stabbing, or knife-like pain
A feeling of heaviness or dull pain in the feet
Redness and excessive heat in the skin
Excessive sensitivity to touch
The severity and duration of symptoms can vary greatly from person to person. While one person may experience a mild and constant burning sensation, another may feel this pain intermittently but more intensely.
What Causes the Sensation of Burning Feet?
One of the main underlying causes of burning feet is "neuropathy," which refers to damage in the nerves. It is seen more frequently in individuals with long-standing diabetes or poorly controlled blood sugar. Nerve damage causes incorrect pain signals to be sent to the brain even if there is no actual wound in the tissue; this manifests as tingling, numbness, and burning sensations in the feet.
In addition, there are other conditions that can cause burning feet:
Chronic kidney disease
Sensory disorders due to involvement of small nerve fibers in the skin (small fiber neuropathy)
Deficiency of vitamins B12, folate, or B6
Excessive alcohol consumption
Low thyroid hormone (hypothyroidism)
Infections such as Lyme disease
Fungal diseases such as athlete's foot
HIV/AIDS
Abnormal protein accumulation in nerves (amyloid polyneuropathy)
Chemotherapy processes
Excess vitamin B6
Side effects of certain medications
Erythromelalgia, which involves dilation of the vessels in the hands and feet
Poisoning with heavy metals such as lead, mercury, arsenic
Vasculitis (inflammation of blood vessels)
Abnormal immune responses to certain tissues (sarcoidosis)
Neurological diseases such as Guillain-Barre syndrome and chronic inflammatory demyelinating polyneuropathy (CIDP)
In some individuals, the cause of burning feet may not be clearly determined despite comprehensive testing.
Why Does Burning in the Feet Intensify at Night?
The sensation of burning in the feet can be felt more intensely, especially at night. While a temporary burning may occur after daily exertion or due to simple causes such as a superficial infection, a frequently recurring and persistent problem may actually be a sign of nerve pathway damage. It is known that nighttime burning in the feet can negatively affect falling asleep and sleep quality. Simple methods that can be applied to alleviate this condition include:
Soaking the feet in mildly warm (not scalding) water for 10-15 minutes
Resting the legs and keeping them elevated
Using pain-relieving medication or creams as recommended by a doctor
Gently massaging the feet
Identifying the Condition Causing Burning Feet
Clarifying the underlying cause of the burning sensation in the feet is important for reaching the correct treatment. However, it is not always possible to objectively measure burning or pain. The following methods are used for diagnosis:
Medical history and physical examination: Your physician collects detailed information about your current health status, medications you use, and symptoms you experience. Additionally, by examining the relevant area, your reflexes, signs of infection, or skin changes are evaluated.
Muscle and nerve tests: Electromyography (EMG) measures the electrical activity of muscles and helps identify underlying muscle or nerve problems. Nerve conduction velocity testing also evaluates the conduction capacity of specific nerves.
Laboratory tests: Blood tests examine various parameters such as blood sugar levels, vitamin levels, kidney and thyroid functions. If necessary, urine or cerebrospinal fluid analyses may also be performed.
Nerve biopsy: Rarely, if diagnosis is difficult, a small sample of nerve tissue may need to be taken and examined microscopically.
Approaches to Follow and Treatment Strategies for Burning Feet
In the treatment of burning feet, the main goal is to clarify the underlying cause and create a roadmap accordingly. For example, in burning feet due to diabetic neuropathy, blood sugar control and prevention of nerve damage are prioritized, while in cases due to fungal infection, antifungal creams are used.
In cases where treatment targeting the cause is not possible or the cause cannot be found, methods focusing on improving the individual's quality of life and alleviating symptoms are applied. General recommendations and treatment options include:
Supplementing deficient vitamins (especially B12, B6, folate) under the guidance of a doctor
Avoiding excessive alcohol consumption
Dialysis treatment if necessary in cases related to kidney disease
Appropriate hormone support in cases of thyroid hormone deficiency
Blood sugar-regulating diet, medication, or insulin therapy in diabetic individuals
Use of pain-relieving medication or topical ointments if necessary
Burning feet syndrome is not a directly life-threatening clinical condition; however, in the long term, it can negatively affect an individual's daily comfort and sleep pattern. Personalized diagnosis and treatment, along with physician recommendations and regular follow-up, can yield successful results.
Frequently Asked Questions
1. What causes a burning sensation in the soles of the feet?
The sensation of burning in the feet usually occurs as a result of nerve damage (neuropathy), vitamin deficiency, diabetes, or alcohol use. Additionally, fungal infection, some metabolic diseases, or rarely, side effects of medications may also be among the causes.
2. Does burning feet go away on its own?
Depending on the cause, it may be temporary in some cases; however, if it is due to nerve damage or a systemic disease, it may be permanent. For prolonged and severe burning, a doctor should definitely be consulted.
3. What can be done at home for burning feet?
In mild cases, resting the feet, avoiding extreme temperatures, keeping them moist, soaking in moderately warm water, and choosing appropriate footwear may be beneficial. If complaints are pronounced, treatment should not be applied without consulting a physician.
4. Why does the burning sensation in my feet increase at night?
Because nerves become more sensitive at night, changes in blood circulation, and attention being directed elsewhere during the day, burning may be felt more at night.
5. What diseases can burning feet be a symptom of?
Diabetic neuropathy, vitamin deficiencies, thyroid disorders, kidney disease, fungal infections, and some neurological and autoimmune diseases can cause burning feet.
6. In which situations should I consult a doctor?
If burning in the feet is accompanied by severe pain, loss of strength, persistent numbness, serious difficulty walking, rapidly progressing complIf these symptoms are accompanied by signs of wounds or infection on the skin, urgent medical evaluation is required.
7. What tests are performed for burning feet?
After taking your medical history, your doctor may plan tests such as blood tests, nerve and muscle function tests, and, if necessary, skin or nerve biopsy.
8. Are vitamin supplements beneficial for burning feet?
Vitamin supplementation at an appropriate dose may be beneficial only in patients with a diagnosed vitamin deficiency, under physician recommendation.
9. Are there any permanent damages caused by burning feet?
If the underlying problem, such as advanced diabetic neuropathy, is not detected and treated in time, permanent nerve damage may occur.
10. Does burning feet occur in children?
Although rare, certain metabolic or neurological problems can also cause burning feet in children. In such cases, evaluation by a pediatrician is necessary.
11. Does the burning occur throughout the entire foot or only in specific areas?
A condition may develop that affects both the sole of the foot and spreads toward the ankle and legs. The location and spread of symptoms may provide clues about the cause.
12. In which other organs can similar sensations develop?
Burning or tingling sensations may develop in the hands and lower legs, and in some cases even in the arms. Such findings may indicate widespread nerve involvement or a systemic disease in the body.
