What is Sciatica?
Sciatica is the general term for pain caused by an inflammation, pinching, or compression of the large, thick sciatic nerve that begins in the lower back and radiates through the hips, buttocks and both legs. Identifying and treating the specific cause of the pain is key to providing patients relief. The most common causes of sciatica, also called lumbosacral radicular syndrome, are herniated disk, slipped disk, and bone spurs that put pressure on the nerve root.
Sciatica is common, with about 40% of people experiencing it at some point in their lives. More than half of pregnant women also experience sciatica symptoms. The vast majority of people with sciatica get better on their own with self-care treatments within a few weeks.
UTHealth Neurosciences’ pain specialist Dr. Hiral Patel and neurosurgeon Dr. Krish Vigneswaran discuss common issues related to back pain and how they are treated.
Causes of Sciatica
Sciatica occurs when a herniated disk or bone spur pinches the sciatic nerve. Age, obesity, and prolonged sitting increase the occurrence of sciatica. It can also be caused by other conditions that put pressure on the sciatic nerve, including stenosis, osteoarthritis, spondylolidthesis, or degenerative disc disease. Cysts and tumors are less common causes of sciatica. Many pregnant women also suffer sciatica symptoms.
Symptoms of Sciatica
Sciatica is characterized by pain that radiates from the lower back down to the buttock and through the back of the leg. Patients may experience pain, numbness, and tingling all the way down to the foot. The degree of pain can vary from a mild cramp to a sharp, burning sensation. Coughing or sneezing can worsen the pain. It may be hard to stand up or move the leg or foot. Patients who experience severe pain, numbness, muscle weakness in the leg, or difficulty controlling bowels or bladder, should schedule an appointment with one of our specialists.
Diagnosis of Sciatica
Your doctor will perform a physical exam, during which they will check your muscle strength and check to see whether pain increases during certain movements of your legs and feet. If the pain is ongoing, an X-ray, CT scan, or MRI may be ordered to check for herniated disks or bone spurs that may be pressing on a nerve. Diagnostic nerve blocks may also be used.
Treatment of Sciatica
The majority of cases of sciatica resolve on their own within a few weeks, but treatment may be needed to decrease pain and increase mobility. Patients can apply ice or heat to help pain relief. Engaging in light activity, without strenuous lifting or long periods of sitting, is also recommended. Prolonged bed rest has little benefit to patients with sciatica. Gentle stretches of the spine and hamstrings may also be beneficial.
In some cases, your specialist may recommend physical therapy, traction therapy, epidural steroid injections, or prescription pain relievers. If you suffer from chronic sciatica, your surgeon may recommend a microdiscectomy or another procedure to remove fragments of a herniated disc.
