What causes a warm sensation from the knees down in both legs?

A common cause of a warm sensation from the knees down in both legs is peripheral neuropathy, which is damage to the nerves that carry messages from the brain and spinal cord to the rest of the body. This can occur due to a variety of factors, including:

- Diabetes: High blood sugar levels can damage the nerves, leading to peripheral neuropathy.

- Alcoholism: Excessive alcohol consumption can also damage the nerves.

- Vitamin B12 deficiency: Vitamin B12 is essential for nerve function, and a deficiency can cause peripheral neuropathy.

- Autoimmune disorders: Certain autoimmune disorders, such as lupus and rheumatoid arthritis, can attack the nerves and cause peripheral neuropathy.

- Infections: Some infections, such as Lyme disease and shingles, can also cause peripheral neuropathy.

Peripheral neuropathy can cause a variety of symptoms, including numbness, tingling, burning, and pain. The warm sensation you are experiencing may be due to damage to the sensory nerves that control temperature regulation.

If you are experiencing a warm sensation from the knees down in both legs, it is important to see a doctor to determine the cause and receive appropriate treatment.
