Sciatica can begin as an occasional ache in the lower back or buttock. Then, sometimes without much warning, the discomfort travels down the leg, making it difficult to sit, stand, walk, or get comfortable.
For some people, the pain is mild and temporary. For others, it becomes sharp, burning, or persistent enough to interfere with work, sleep, and everyday activities.
The important thing to understand is that sciatica isn’t actually a diagnosis by itself. It’s a term used to describe symptoms caused by irritation or compression of nerves associated with the sciatic nerve.
Sciatica commonly occurs when a nerve root in the lower spine becomes irritated or compressed. Herniated discs, spinal stenosis, and age-related changes in the spine are among the possible causes. While many cases improve with conservative treatment, persistent pain, worsening numbness, or muscle weakness should be evaluated by a qualified medical professional.
For patients in Dallas, Plano, and surrounding North Texas communities, understanding what’s causing the symptoms is the first step toward finding an appropriate treatment.
What Is Sciatica?
The sciatic nerve is the largest nerve in the body. It forms from nerve roots in the lower spine and travels through the buttock and down the leg.
When one or more of those nerve roots becomes irritated or compressed, pain and other symptoms can travel along the affected nerve pathway.
Sciatica usually affects one side of the body, although symptoms can sometimes occur on both sides.
Common symptoms include pain in the lower back or buttock that radiates into the leg, tingling, numbness, burning sensations, and occasionally muscle weakness.
Some people experience more discomfort in the leg than in the back.
That can make sciatica confusing because the location of the pain isn’t always where the underlying problem begins.
What Are the Most Common Causes of Sciatica?
Several conditions can irritate or compress the nerves in the lower spine.
Identifying the cause matters because the appropriate treatment depends on the underlying condition, severity of symptoms, and findings from the examination.
1. Herniated Lumbar Disc
A herniated disc is one of the more common causes of sciatica.
The discs between the vertebrae help absorb shock and allow movement.
When part of a disc pushes beyond its normal boundary, it may irritate or compress a nearby nerve root.
This can produce pain that travels from the lower back through the buttock and down the leg.
Symptoms may become more noticeable with certain movements, prolonged sitting, coughing, or sneezing.
Not every herniated disc causes sciatica, and not every case of sciatica is caused by a herniated disc.
2. Lumbar Spinal Stenosis
Spinal stenosis occurs when spaces within the spinal canal or around the nerves become narrowed.
This narrowing can place pressure on the nerve structures.
People with lumbar spinal stenosis may experience leg pain, numbness, tingling, or weakness, particularly when standing or walking.
Some notice that symptoms improve when sitting or leaning forward.
Spinal stenosis becomes more common with age and may develop alongside other degenerative changes.
3. Degenerative Changes in the Spine
As people age, the discs and joints of the spine naturally change.
Discs may lose height, joints may develop arthritis, and bone spurs may form.
These changes can narrow the openings through which nerves exit the spine.
When a nerve becomes irritated or compressed, symptoms resembling sciatica may develop.
4. Spondylolisthesis
Spondylolisthesis occurs when one vertebra slips forward relative to another.
Depending on the degree of slippage and surrounding anatomy, the condition may contribute to narrowing around the spinal nerves.
Some people experience primarily lower back discomfort, while others develop radiating leg pain or neurological symptoms.
5. Other Causes of Sciatic-Type Pain
Not all pain traveling through the buttock and leg originates from a compressed spinal nerve.
Certain hip conditions, peripheral nerve problems, and irritation of the sciatic nerve outside the spine can produce similar symptoms.
This is one reason a careful medical evaluation matters.
Treating every case of radiating leg pain as a herniated disc can overlook other possible causes.
What Does Sciatica Pain Feel Like?
Sciatica doesn’t feel exactly the same for everyone.
Some patients describe a dull ache. Others report an electric shock, burning sensation, or sharp pain shooting down the leg.
Symptoms may include:
-
Pain traveling from the buttock into the thigh, calf, or foot
-
Tingling or a pins-and-needles sensation
-
Numbness in part of the leg or foot
-
Burning or shooting pain
-
Difficulty sitting comfortably
-
Pain that increases with certain movements
-
Weakness involving the affected leg or foot
The symptoms can vary depending on which nerve root is involved and how severely it is affected.
How Can You Tell if Leg Pain Is Sciatica?
Pain traveling down the leg is a common feature of sciatica, but the pattern alone doesn’t establish the diagnosis.
A medical professional may ask where the pain begins, how far it travels, whether numbness or weakness is present, and which activities make symptoms better or worse.
A physical examination may include checking reflexes, muscle strength, sensation, walking ability, and movements that reproduce symptoms.
These findings help determine whether the pain is likely related to nerve irritation in the spine or another condition.
Which Sciatica Symptoms Should Not Be Ignored?
Many cases improve over time, but certain symptoms deserve prompt medical attention.
Persistent or worsening leg pain: Pain that continues despite reasonable self-care or interferes with normal activities should be evaluated.
Increasing numbness: Progressive sensory changes can indicate ongoing nerve involvement.
Muscle weakness: Difficulty lifting the front of the foot, walking on the heels or toes, or maintaining normal leg strength warrants medical evaluation.
Symptoms affecting daily activities: Pain that significantly limits walking, standing, working, or sleeping may require a more individualized treatment plan.
Sudden or progressive weakness should be assessed urgently.
When Is Sciatica a Medical Emergency?
Certain symptoms can indicate serious compression of nerves in the lower spine.
Seek emergency medical care immediately if sciatica-like symptoms occur with new difficulty urinating or loss of bladder or bowel control, numbness around the groin or saddle area, or rapidly progressing leg weakness.
These can be warning signs of cauda equina syndrome or another serious neurological condition.
Severe symptoms following significant trauma also require urgent evaluation.
When Should You See an Orthopedic or Spine Specialist for Sciatica?
An orthopedic spine specialist may be appropriate when symptoms persist, recur, worsen, or involve neurological changes.
A specialist can help determine whether the symptoms are related to a herniated disc, spinal stenosis, degenerative changes, or another condition.
Patients may benefit from specialist evaluation when:
-
Radiating leg pain persists for several weeks or significantly disrupts daily life
-
Symptoms repeatedly return
-
Numbness or tingling is increasing
-
Muscle weakness develops
-
Initial conservative treatment has not provided sufficient improvement
-
Imaging suggests a condition that may require more specialized treatment
A referral doesn’t automatically mean surgery will be recommended.
In many cases, the goal is to understand the problem and identify the most appropriate nonsurgical treatment.
How Is Sciatica Diagnosed?
Diagnosis generally begins with a medical history and physical examination.
The specialist evaluates the pattern of symptoms and looks for signs of nerve involvement.
Depending on the findings, additional testing may be appropriate.
Physical Examination
The examination may include assessment of muscle strength, reflexes, sensation, walking, and spinal movement.
Certain leg-positioning tests may help determine whether a nerve root is irritated.
MRI
An MRI can provide detailed images of discs, nerves, and other soft tissues.
It may be recommended when symptoms persist despite treatment, neurological deficits are present, or the findings could change treatment decisions.
Not every patient with sciatica needs an MRI immediately.
X-Rays and Other Testing
X-rays can help identify certain structural changes, although they do not directly show disc herniations or nerve compression.
In selected cases, other imaging or electrodiagnostic testing may help clarify the diagnosis.
What Treatment Options Are Commonly Used for Sciatica?
Treatment depends on the cause and severity of symptoms.
Many patients improve without surgery.
Activity Modification
Remaining reasonably active is often preferable to prolonged bed rest.
Temporary changes to activities that aggravate symptoms may help while the condition improves.
The objective is to maintain movement without repeatedly provoking significant pain.
Physical Therapy
Physical therapy may help improve mobility, strengthen supporting muscles, address movement limitations, and develop strategies for returning to normal activities.
Treatment should be individualized because exercises that help one patient may aggravate another.
Medications
Depending on the patient’s medical history and symptoms, a medical professional may recommend appropriate medications to help manage pain or inflammation.
Medication choices should account for other health conditions, current prescriptions, and potential side effects.
Epidural Steroid Injections
For selected patients with significant radiating nerve pain, an epidural steroid injection may be considered.
These injections can sometimes provide temporary symptom relief, potentially making rehabilitation and normal activity easier.
They do not correct every underlying structural problem.
Surgery
Surgery may be considered when symptoms remain disabling despite appropriate conservative treatment or when significant neurological problems are present.
The procedure depends on the underlying condition.
For example, a lumbar disc herniation causing persistent nerve compression may sometimes be treated with a microdiscectomy.
Certain cases of spinal stenosis may require a decompression procedure.
Surgical decisions should be based on the patient’s symptoms, examination, imaging, overall health, and treatment goals.
Does Sciatica Always Require Surgery?
No.
Many people improve with time and nonsurgical treatment.
Even when imaging reveals a herniated disc, surgery isn’t automatically necessary.
The decision depends on whether the symptoms are improving, how much they affect daily life, whether neurological deficits are present, and how the findings relate to the patient’s symptoms.
A spine specialist can help patients understand when continued conservative treatment is reasonable and when another approach should be considered.
Can Sciatica Come Back After Treatment?
Yes.
Sciatica can recur, particularly when underlying degenerative changes or other contributing conditions remain present.
That doesn’t mean treatment has failed.
Long-term management may involve maintaining appropriate physical activity, strengthening supporting muscles, modifying aggravating activities, and addressing recurring symptoms before they become more severe.
Patients with repeated episodes may benefit from a more detailed evaluation of the underlying cause.
Frequently Asked Questions About Sciatica
What is the most common cause of sciatica?
A herniated lumbar disc is a common cause, particularly in younger and middle-aged adults. Spinal stenosis and degenerative spinal changes are also important causes, especially in older adults.
Can sciatica cause numbness in the foot?
Yes. Irritation or compression of certain lower-spine nerve roots can cause tingling or numbness extending into the foot.
How long does sciatica usually last?
Many cases improve over several weeks, although recovery varies. Some patients experience symptoms that persist for months or recur over time.
Can walking help sciatica?
Gentle walking may be beneficial for some patients, but the response depends on the cause. For example, people with certain forms of spinal stenosis may experience increased symptoms during walking.
Is sciatica caused by the hip or the back?
Sciatica most commonly results from irritation of nerve roots in the lower spine, but hip and other conditions can sometimes cause similar pain. An examination helps distinguish among possible causes.
When should I see a spine specialist in Dallas for sciatica?
Consider evaluation when pain persists, worsens, repeatedly returns, or interferes with daily activities. New weakness or progressive neurological symptoms require more urgent assessment.
