Sciatica, medically known as lumbar radiculopathy, is not a disease in itself, but a symptom of an underlying problem affecting the sciatic nerve. This nerve originates in the lower back and extends through the buttocks and down the back of each leg. The sciatic nerve is the largest nerve in the body. It is formed by the union of part of the lumbar and sacral nerve roots. Sciatica occurs when this nerve is compressed or irritated, usually by a herniated disc.
The symptoms of sciatica can vary in intensity, from mild discomfort to severe and debilitating pain. The most characteristic symptom is a sharp, stabbing, or burning pain that radiates from the lower back, through the buttock, and down the back of the leg. Other symptoms may include:
Pain that radiates from the lower back to the buttock and leg.
Numbness, tingling, or weakness in the leg or foot.
Pain that worsens when sitting, coughing, sneezing, or bending the spine forward.
Difficulty moving the leg or foot.
Unilateral symptoms; sciatica usually affects one leg. Both legs are rarely affected.
Sciatica can be classified according to its cause, duration, and severity. It can be acute (short-term), chronic (long-term), or recurrent (coming and going). Classification helps guide the treatment and management of the condition.
Sciatica is usually caused by compression or irritation of the nerve roots that form the sciatic nerve. The most common cause is a lumbar herniated disc, where the disc material shifts and presses on the nerve. Other less common causes include spinal stenosis, bone osteophytes, lumbar degenerative disc disease, spondylolisthesis, sacroiliac joint dysfunction, and piriformis syndrome.
A risk factor is any characteristic or circumstance that increases the likelihood of developing a disease or condition. In the case of sciatica, several risk factors can contribute to its onset or worsen existing symptoms. Some of these factors are:
While most people recover from sciatica without long-term problems, some may experience side effects. Chronic pain is one of the most common complications and can persist even after the underlying cause has been resolved. Muscle weakness in the affected leg or foot can make mobility and balance difficult. Persistent numbness or tingling can be bothersome and interfere with daily activities. In rare cases, sciatica can progress to cauda equina syndrome, a serious condition that compresses the nerves in the lower spine and can cause paralysis or weakness of the lower limbs, urinary or fecal incontinence, and even sexual dysfunction. This condition requires immediate medical attention.
The diagnosis of sciatica involves a thorough evaluation by a doctor, which includes:
At HM Hospitales, we use state-of-the-art technology for the diagnosis of sciatica, including high-resolution magnetic resonance imaging and electromyography.
The treatment for sciatica varies depending on the cause and severity of the symptoms. The goal of treatment is to relieve pain, improve function, and prevent recurrence. Treatment options include:
At HM Hospitales, we have a spine unit comprised of neurosurgeons and traumatologists specializing in the spine, among other medical professionals.
