Burning Feet: Neurological Causes and Solutions

Burning sensation in the soles of the feet?

I constantly feel a burning sensation in the soles of my feet, and they become sore and weak after standing for a long time.
I have consulted various specialists, but no cause has been identified.
Could you please advise if there might be an issue, or which specialty I should consider for further evaluation? Thank you.

Dear Miss Su,
You mentioned that "the soles of my feet feel hot all the time," which is a symptom associated with peripheral neuropathy.
Symptoms of peripheral nerve compression include: 1.
Pain characterized by burning sensations and tingling; 2.
Symptoms that have a specific band-like distribution, which can be triggered by touch or pressure; 3.
Accompanied by muscle weakness and fatigue.
Blood tests should include screening for possible complications such as anemia, hyperthyroidism/hypothyroidism, diabetes, autoimmune diseases, and neurosyphilis, among others.

Peripheral nerve examinations can typically utilize electrophysiological studies to assist in diagnosis.
Nerve conduction studies assess the conduction velocity and waveform of large fiber nerves.
Electromyography evaluates muscle responses in the areas supplied by the nerves.
It is advisable to consult a neurologist specializing in peripheral nerves, as they have more experience with electromyography diagnostics.
Thank you for your inquiry, and feel free to discuss any related questions further! Wishing you good health, peace, and happiness.
Dr.
Jiang Junyi, Neurologist at Taoyuan Hospital, cares about you.

More Info

Burning feet, or the sensation of heat in the soles of the feet, can be a perplexing and uncomfortable symptom that may arise from various neurological, vascular, or metabolic issues. Understanding the potential causes and appropriate avenues for investigation is crucial for effective management.

One common neurological cause of burning feet is peripheral neuropathy, which is often associated with conditions such as diabetes, vitamin deficiencies (especially B vitamins), and certain autoimmune diseases. Peripheral neuropathy occurs when the peripheral nerves, which transmit signals between the central nervous system and the rest of the body, become damaged. This damage can lead to sensations of burning, tingling, or numbness, particularly in the extremities.

In your case, since you have already consulted multiple specialties without a definitive diagnosis, it may be beneficial to revisit a neurologist. A neurologist specializes in disorders of the nervous system and can conduct specific tests, such as nerve conduction studies or electromyography (EMG), to assess the function of your peripheral nerves. These tests can help identify any nerve damage or dysfunction that may be contributing to your symptoms.

Additionally, consider the possibility of other underlying conditions that could lead to burning feet. For instance, conditions like hypothyroidism, chronic kidney disease, or even certain infections can manifest with similar symptoms. A thorough evaluation of your medical history, along with blood tests to check for metabolic or systemic issues, may provide further insights.

Another aspect to consider is the role of lifestyle factors. Prolonged standing or walking, especially in inappropriate footwear, can lead to foot pain and discomfort. Ensuring that you wear supportive shoes and take breaks to rest your feet can help alleviate some of the strain. Furthermore, maintaining a healthy diet and staying hydrated can support overall nerve health.

If the burning sensation is accompanied by other symptoms, such as swelling, redness, or changes in skin color, it may indicate a vascular issue, such as peripheral artery disease. In such cases, consulting a vascular specialist may be warranted.

In summary, burning feet can stem from various causes, with peripheral neuropathy being a common neurological culprit. A comprehensive evaluation by a neurologist, along with consideration of other potential underlying conditions, is essential for accurate diagnosis and effective treatment. Addressing lifestyle factors and ensuring proper foot care can also play a significant role in managing symptoms. If you continue to experience discomfort, do not hesitate to seek further medical advice to explore all possible avenues for relief.
