Some people experience a burning sensation in their feet when they lie down to sleep. It may feel like heat under the skin, pins and needles or an uncomfortable tingling sensation. While temporary discomfort can have simple explanations, persistent burning deserves attention.
1. Nerve damage associated with diabetes
High blood sugar over time can damage nerves, particularly those in the feet. This may cause burning, tingling, numbness or pain that becomes more noticeable at night.
2. Vitamin B12 deficiency
Vitamin B12 is important for healthy nerve function. Low levels can contribute to nerve problems, including unusual sensations in the hands and feet.
3. Tight footwear
Shoes that are too tight can place pressure on the feet and irritate nerves. Wearing properly fitted footwear may help prevent discomfort.
4. Alcohol-related nerve damage
Long-term excessive alcohol consumption can damage nerves and contribute to burning or tingling sensations in the feet.
5. Other nerve and circulation conditions
Some spinal problems, nerve disorders and circulation conditions can affect the feet. A healthcare professional may need to examine you to identify the cause.
Final thoughts
Avoid ignoring persistent burning sensations, particularly if you also experience numbness, weakness or wounds that heal slowly. A medical assessment may include blood tests and examination of nerve function. Sudden severe pain, a cold or discoloured foot, or a wound showing signs of infection needs prompt attention.
