Burning Sensation in Leg Below Knee: Causes & Treatment

What causes a burning sensation in leg below knee?

There are several potential causes for burning sensations in the leg below the knee. Let’s take a closer look at each:

Nerve damage

Nerve damage, also known as peripheral neuropathy, can lead to a burning sensation in the leg. Conditions such as diabetes, vitamin deficiencies, and certain medications can cause nerve damage. When the nerves are affected, they may send abnormal signals to the brain, resulting in burning legs.

Peripheral artery disease (PAD)

Peripheral artery disease (PAD) occurs when the arteries in the legs become narrowed or blocked, reducing blood flow. This can lead to a burning sensation due to inadequate oxygen and nutrients reaching the leg muscles.

Muscle fatigue and overuse

Engaging in strenuous physical activities or overusing the leg muscles can lead to muscle fatigue. This can cause a burning sensation due to the buildup of lactic acid and the strain placed on the muscles.

Spider veins

Spider veins, also known as telangiectasias are smaller, web-like veins that can cause a hot or burning sensation in the legs. They are typically closer to the surface of the skin and are commonly seen on the legs, hands, stomach, and buttocks.

Restless leg syndrome (RLS)

Restless leg syndrome (RLS) is a neurological disorder characterized by an uncontrollable urge to move the legs. People with RLS often experience uncomfortable sensations, including burning, tingling, or itching, especially during periods of inactivity or at night.

Varicose veins

Varicose veins are enlarged, swollen veins that usually appear on the legs and can cause a burning or throbbing pain sensation. They occur when the vein valves weaken, which allows proper blood flow back to the heart, causing blood to pool and veins to become enlarged.

Deep vein thrombosis (DVT)

Deep vein thrombosis is a blood clot that forms in a deep vein, commonly in the leg. Deep vein thrombosis can cause a sudden and severe burning sensation, along with swelling, warmth, and redness in the affected area. It is a serious condition that requires immediate medical attention.

Certain factors can increase the likelihood of experiencing a burning sensation in the legs below the knee. These include:

• Obesity

Burning sensation in the leg below knee home remedies

When you experience a burning sensation in your leg below the knee, it can be quite uncomfortable. Fortunately, there are several home remedies that you can try to alleviate the discomfort.

• Elevate your leg: Propping up your leg on a pillow or cushion can improve blood circulation and reduce swelling, which may contribute to the burning sensation.
• Apply a cold compress: Placing a cold compress, such as an ice pack or a bag of frozen peas, on the affected area can help reduce inflammation and numb the pain.
• Practice gentle exercises: Engaging in low-impact exercises like walking or stretching can increase blood flow and relieve the warm sensation in your legs. Additionally, this can help strengthen your leg muscles and relieve pain that commonly accompanies warm feeling in the lower legs.
• Compression stockings: Wearing compression stockings can effectively alleviate the burning sensation in your leg below the knee. These specially designed stockings apply gentle pressure to your lower legs, improving blood circulation and preventing blood from pooling in the veins, which can contribute to the burning legs sensation.
• Maintaining a Healthy Weight: Excess weight can strain your legs, leading to a burning sensation. By maintaining a healthy weight through a balanced diet and regular exercise, you can alleviate the pressure on your legs. This will not only reduce the burning sensation but also improve your overall leg health.

How to treat a burning sensation in legs below the knees caused by venous disease?

If venous disease, such as varicose veins or spider veins, is causing a leg burning sensation, medical treatment may be necessary. These medical treatments may include minimally invasive procedures like sclerotherapy, laser treatment, and radiofrequency ablation (RFA). These techniques target the underlying cause of the burning sensation and can provide long-term relief.
