Most often, neuropathy is the cause of burning feet. Damaged nerve fibers are more likely to become overactive and misfire.
The damaged nerves send pain signals to the brain even though there is no wound.
In most people with neuropathy, the leg nerves become damaged first. These people often have tingling and numbness in the feet as well. Many people complain that their feet are overly sensitive to touch (hyperesthesia) and can have varying degrees of burning pain. It can range from mild to disabling.
Diabetes and alcohol abuse are by far the most common causes of neuropathy in the legs. Many other conditions can cause neuropathy or a burning sensation in the feet:
- Chronic kidney disease (uremia)
- Small fiber neuropathy
- Vitamin deficiency (vitamin B12, folate, and occasionally vitamin B6)
- Alcohol abuse
- Low thyroid hormone levels (hypothyroidism)
- Lyme disease
- Amyloid polyneuropathy
- Drug side effects, including chemotherapy drugs, vitamin B6 overdose, HIV medicines, amiodarone, isoniazid, metformin, and others
- Heavy metal poisoning (lead, mercury, arsenic)
- Vasculitis (inflammation of blood vessels)
- Guillain-Barre syndrome (GBS)
- Chronic inflammatory demyelinating polyneuropathy (CIDP)
Besides neuropathy, infections and inflammation of the feet can also cause a burning sensation. The most common of these is athlete's foot, an infection of the skin caused by fungus.
Peripheral artery disease (PAD) also commonly causes burning feet. The poor circulation of blood to the feet may frequently cause pain, tingling, and burning feet, especially while walking.
Weeks or months after gastric bypass surgery, some people experience a burning feet sensation. Poor absorption of B vitamins after gastric bypass can cause neuropathy in the legs and a sensation of burning feet.
