Foot burning is a frequent symptom that can be caused by a number of underlying illnesses. It is distinguished by a burning, tingling, or numb feeling in the feet that can range from moderate to severe. Other symptoms such as discomfort, irritation, or sensitivity to touch may accompany it.
- Peripheral artery disease
The arteries that provide blood to the legs and feet become constricted or obstructed in peripheral arterial disease (PAD). A burning sensation or discomfort in the feet or toes is a frequent sign of PAD, especially when walking or exercising. Leg cramps, weariness, and numbness or tingling are some of the other symptoms. PAD is caused by plaque accumulation in the arteries, which is often caused by excessive cholesterol, high blood pressure, and smoking.
Diabetes is a common cause of foot burning. It develops as a result of nerve damage (neuropathy) induced by high blood sugar levels over time. This injury can disrupt the nerves that send feeling to the foot, causing burning, numbness, tingling, and pain. Diabetes can also result in impaired circulation, which can create a burning feeling in the feet. Diabetes patients are also more likely to develop additional foot issues such as calluses, blisters, and foot ulcers, which can cause burning or discomfort.
- Plantar fasciitis
Burning or discomfort in the heel can be caused by plantar fasciitis, an inflammation of the tissue on the bottom of the foot.
- Rheumatoid arthritis
Rheumatoid arthritis can cause a burning feeling and discomfort in the feet, especially if the illness affects the tiny joints of the feet and toes. This can cause the foot to become swollen and sensitive, making walking or standing difficult.
Gout is a kind of arthritis in which uric acid crystals accumulate in the joints, producing inflammation and discomfort. One of the most common symptoms of gout is extreme pain and burning in the afflicted joint, which is usually the big toe, although it can also affect ankles, knees, and fingers. The afflicted region may also be swollen, red, and painful to the touch. Gout pain and burning feeling are generally worst at night, and it may take a few days for the agony to go away. Gout is caused by uric acid accumulation in the body, which can be caused by genetics, nutrition, or certain medical conditions.
- Deficiency of vitamin B12
A lack of vitamin B12 can also induce foot burning and other neurological symptoms.
Alcoholism, also known as alcohol use disorder, can result in a burning feeling or discomfort in the foot due to a disease known as alcoholic neuropathy. This is a kind of peripheral neuropathy caused by persistent excessive alcohol intake, which causes nerve damage and symptoms such as burning, tingling, numbness, and weakness in the feet and lower legs.
Diabetes, drunkenness, and certain drugs can all induce neuropathy, which causes a burning feeling in the feet.
- Thyroid disorders
Thyroid problems, including hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid), can result in a burning feeling or discomfort in the feet due to a condition known as peripheral neuropathy. This is a form of nerve injury that can produce symptoms such as burning, tingling, numbness, and weakness in the feet, legs, and hands.
- Medications used to treat high blood pressure and depression.
As a side effect, several drugs used to treat high blood pressure and depression might induce burning or tingling in the feet. Thyroid issues can also produce foot burning, among other symptoms.
