Sciatica (Lumbar Radiculopathy): Symptoms, Causes, and How to Fix It
Sciatica, known medically as lumbar radiculopathy, is pain, numbness, or tingling that travels from your lower back or buttock down the leg, caused by irritation of a nerve root in the lower spine. The reassuring part: the large majority of cases get better without surgery, and physical therapy is one of the most effective treatments. This guide explains what sciatica and lumbar radiculopathy are, the symptoms, what causes it, and how physical therapy relieves it.
What is sciatica (lumbar radiculopathy)?
Sciatica and lumbar radiculopathy are two names for the same problem: a nerve root in your lower back gets compressed or irritated, and the symptoms travel along that nerve down the leg. "Sciatica" is the everyday term because the sciatic nerve is often involved; "lumbar radiculopathy" is what a doctor writes because it describes a lumbar (lower back) nerve root that is affected. It is a symptom of an underlying issue in the spine, not a diagnosis on its own, which is why finding the cause matters.
Sciatica always starts with an irritated nerve, but the irritation can happen in more than one place. Most of the time the problem is in the spine itself: a herniated or bulging disc pressing on the nerve root is the most common cause, followed by spinal stenosis, which is a narrowing of the space around the nerve, age-related disc wear, bone spurs, or spondylolisthesis, where a vertebra slips slightly forward on the one below it. Less often, the nerve gets irritated further along its path, outside the spine. The classic example is a tight or overworked piriformis, a deep muscle in the buttock that the sciatic nerve runs directly beneath; when it clamps down, it can reproduce the same shooting leg pain even though the spine is fine. Part of the evaluation is figuring out which of these is your driver, because a disc problem, a narrowed canal, and an angry piriformis are all treated differently.
Sciatica symptoms
The most common sciatica symptoms are pain that runs from the lower back, buttock or hip down the back or side of the leg, often past the knee, sometimes with numbness, tingling, or a "pins and needles" feeling, and in more severe cases weakness in the leg or foot. Common patterns include:
- Pain that travels from the low back or buttock down one leg, frequently past the knee.
- Numbness, tingling, or a "pins and needles" feeling along the same path.
- Weakness in the leg or foot in more severe cases.
- Symptoms on one side that worsen with sitting, bending forward, coughing, or sneezing.
The leg symptoms are frequently more bothersome than the back pain itself, and that is often the clue that a nerve root is involved.
What causes sciatica?
Sciatica happens when there is compression on a lower-spine nerve root or the sciatic nerve, leading to irritation. The most common causes are a herniated or bulging disc pressing on the nerve, age-related narrowing of the space around the nerve called spinal stenosis, and general wear of the spine. Tight or overworked muscles in the hip and buttock can add to the irritation. Prolonged sitting and sudden lifting or twisting often set it off.
In practice, those diagnoses usually trace back to a specific moment or a specific lifestyle. A herniated disc is the classic gym and job-site injury: a heavy deadlift or squat with the low back rounded, lifting a couch or a patient with a twist, or years of repetitive bending and loading in construction, nursing, or warehouse work. Car accidents are another common trigger, since the combination of sudden impact and a braced body can injure a disc or violently compress an already-narrow space around the nerve, which is why sciatica often shows up days after a rear-end collision. Rotational sports like golf, tennis, and baseball load the discs with speed and torque, while a spondylolisthesis often has roots in sports that repeatedly arch the spine, like gymnastics, dance, or football linemen work. On the other end of the spectrum, sciatica also comes from doing too little: long-haul drivers and desk workers who sit eight-plus hours a day put sustained pressure on the discs and let the hips stiffen, and spinal stenosis and bone spurs are usually not one injury at all but decades of accumulated wear finally narrowing the nerve's space. Same symptom down the leg, very different starting points, which is why the story of how yours began matters in the evaluation.
How physical therapy treats sciatica
Most sciatica improves without surgery. Research and clinical guidelines show that the majority of cases respond well to conservative care, especially physical therapy, with many people improving within about four to six weeks and recovery continuing over the following months depending on the severity of the injury. Treatment focuses on calming the irritated nerve, finding the positions and movements that reduce your leg symptoms, and then restoring the mobility, core, and hip strength that take pressure off the nerve. Many people have a clear directional preference that helps relieve symptoms, and that directional preference shapes the treatment plan, easing compression on the nerve and giving it room and blood flow to heal. Surgery is reserved for the minority of cases that do not respond or that involve significant, progressive weakness.
In my practice, when a patient comes in with sciatica or radicular symptoms, the first thing I check is positional preference to find whether they are more aggravated or relieved by a certain position, which helps guide our treatment plan. This is followed by special tests that help rule out certain conditions, such as piriformis syndrome, and a review of imaging, such as an MRI if one has been taken. This helps us come up with a game plan tailored toward your needs and recovery.
Movement and exercise for sciatica
The right movement for sciatica is targeted, not generic. It usually includes finding a direction of movement that eases the leg symptoms, nerve-gliding exercises to calm the irritated nerve, and progressive core, trunk, and hip strengthening to support the spine. Building that strength back up follows the same progressive loading principles we use across rehab: gradual, well-dosed, and matched to what the nerve tolerates. Prolonged bed rest tends to make sciatica worse, so gentle, guided movement in a pain-easing direction is the goal, not pushing into positions that shoot pain down the leg.
Manual therapy and dry needling for sciatica
Alongside the movement plan, hands-on treatment helps settle sciatica down. Manual therapy and joint mobilizations restore movement in a stiff, guarded lower back. When the glutes, piriformis, and low-back muscles clamp down around an irritated nerve, dry needling with electrical stimulation releases those trigger points, calms the pain signaling, and drives blood flow into the area, while cupping and scraping ease the surrounding tension. None of this replaces the movement and strengthening, it makes you comfortable enough to move well and take pressure off the nerve. That combination of hands-on care and targeted loading is the core of how we work at Reclaim Physical Therapy.
When to see a physical therapist for sciatica
See a physical therapist if leg pain, numbness, or tingling from your back is not improving after a week or two, keeps returning, or limits what you can do. A good evaluation pinpoints where the nerve is involved and which movements calm it, so your plan is built around your spine rather than generic stretches. Seek emergency care right away, however, if you develop loss of bowel or bladder control, numbness in the groin or saddle area, or rapidly worsening leg weakness, which are rare but urgent warning signs.

Frequently asked questions
Is sciatica the same as lumbar radiculopathy?
Yes. "Sciatica" is the everyday term and "lumbar radiculopathy" is the medical one, both describing an irritated lower-spine nerve root that sends symptoms down the leg.
Does sciatica need surgery?
Usually not. Most cases improve with conservative care like physical therapy. Surgery is reserved for cases that do not respond or involve significant, progressive weakness.
How long does sciatica take to heal?
Many people improve within four to six weeks, with recovery continuing over the following months. However, recovery time depends on the diagnosis and severity, so some cases settle faster and others take longer.
What makes sciatica worse?
Prolonged sitting, bending forward, and sudden lifting or twisting often aggravate it. Prolonged bed rest also tends to slow recovery.
