3 serious diseases with warning signs of leg numbness

Most cases of leg numbness are nothing to worry about. This condition is often caused by sitting in the wrong position, standing for a long time, or putting pressure on the nerves. When changing positions or doing light exercise, the numbness will disappear after a few minutes, according to the health website Medical News Today (UK).

Spinal nerve compression is a common cause of persistent numbness and tingling in the feet.

However, if leg numbness occurs frequently, lasts a long time, or is accompanied by unusual symptoms such as sharp pain, muscle weakness, or loss of balance, it may be a sign of a more serious health problem. These problems may include:

Spinal instability

The spine is a vital part of the nervous system. Therefore, any changes in the spine can cause numbness in the limbs, especially the feet.

Some spinal problems that can lead to this symptom are herniated disc, sciatica, and spinal stenosis. Herniated disc occurs when the nucleus pulposus inside the spinal disc slips out, possibly pressing on the surrounding nerves.

Sciatica, on the other hand, is caused by irritation or compression of the sciatic nerve, often caused by a herniated disc, spinal stenosis, or bone spurs. Common symptoms of sciatica include numbness, tingling, or pain that radiates from the lower back down to the feet. Spinal stenosis is a condition in which the spinal canal narrows, compressing the nerve, leading to numbness and weakness in the legs and feet.

Tarsal tunnel syndrome

Tarsal tunnel syndrome occurs when the posterior tibial nerve is compressed as it passes through the tarsal tunnel, a narrow opening inside the ankle. Symptoms include numbness, burning, tingling, or sharp pain in the ankle, heel, and foot. Causes of tarsal tunnel syndrome include flat feet, varicose veins, or swelling from an injury.

Peripheral neuropathy

Peripheral neuropathy is a condition in which the peripheral nerves are damaged or dysfunctional. This affects the transmission of signals between the central nervous system and the body, causing numbness, tingling, or pain in the feet and hands.

The most common cause of the disease is diabetes. However, certain factors such as thyroid disorders, rheumatoid arthritis, alcoholism, chemotherapy, or side effects of certain medications can also increase the risk of peripheral neuropathy, according to Medical News Today .
