Have you ever experienced sudden back pain followed by weakness in your legs when walking, or even collapsing to the ground unintentionally? Patients might think it's just leg fatigue or muscle weakness, but medically, these symptoms could be a sign of "severe disc herniation compressing a nerve," requiring immediate treatment. If left untreated, it can affect walking or even lead to disability.

Common symptoms and effects.

My legs went weak rapidly.

Patients will feel a loss of control over their leg muscles. They may experience a feeling of their legs locking up or unexpectedly collapsing, making it increasingly difficult to stand up or walk.

Staggering and easily falling.

Significantly impaired balance increases the risk of falls and injuries, especially in older adults or those with underlying health conditions.

Numbness and unusual sensations in the legs and feet.

A sensation like being pricked by needles, or a tingling or dull ache, occurs along with weakness.

Problems with bowel control.

In severe cases, urinary or fecal incontinence may occur, which is a medical emergency requiring immediate medical attention.

Impact on quality of life.

These severe symptoms can cause patients to become dependent on others for daily routines, lose their independence, and may lead to stress and anxiety.

Causes of this symptom

Severe weakness and inability to walk in the limbs is often caused by...

• Severe nerve compression

For example, severe compression of the spinal cord or nerve roots.

• Severe herniated disc.

Nerve compression can damage leg muscles and impair their function.

• Severe complications

For example, infections or injuries that damage nerves.

Treatment and diagnostic guidelines.

Patients experiencing severe pain leading to leg weakness and inability to walk should receive urgent care from a specialist physician. A thorough physical examination will be conducted, along with the use of advanced diagnostic tools such as X-rays and MRI to assess the severity of nerve compression and the location of any abnormal intervertebral discs.

With our combined treatment experience, cutting-edge technology, and comprehensive equipment at S Hospital, a specialized spine and joint hospital, our doctors will plan treatment to reduce nerve compression using minimally invasive surgery (MIS) and special techniques for installing bone fusion devices in cases of displacement.

This technique minimizes damage to surrounding tissues, promotes faster recovery, and reduces potential complications. Following surgery, patients undergo physical therapy to strengthen muscles, helping them return to their normal lives more quickly.

Small wound, minimal blood loss.

No open surgery is required; a small 1-millimeter needle is used to puncture the problem area, resulting in a very small scar and minimal blood loss.
