Your primary care doctor is usually the first doctor to treat sciatica, and for most people, the only one needed. Around 80% to 90% of sciatica cases resolve with conservative treatment within several weeks, so the initial visit often focuses on confirming the diagnosis, managing pain, and monitoring for warning signs that would call for a specialist.
Starting With Your Primary Care Doctor
A family physician or internist can diagnose sciatica through a focused physical exam without any imaging. The key test is the straight leg raise: you lie on your back while the doctor lifts your affected leg with the knee kept straight. Pain shooting down your leg when it’s raised to less than 45 degrees is a strong indicator of a compressed nerve root, typically at the L5 or S1 level. The doctor will also check muscle strength in your thigh, hamstring, and foot, test your reflexes at the knee and ankle, and compare both sides.
This test is highly sensitive, meaning it’s good at catching disc-related sciatica when it’s there. Its specificity is low, though, so a positive result doesn’t guarantee a herniated disc is the cause. That’s one reason doctors don’t rush to order an MRI. Current guidelines from the American Academy of Family Physicians recommend holding off on imaging for the first six weeks unless red flags are present. If your symptoms haven’t improved after four to six weeks of pain management and physical therapy, an MRI becomes the next step.
During that initial window, your primary care doctor will typically prescribe anti-inflammatory medications, recommend activity modifications, and refer you to physical therapy. This conservative approach resolves symptoms for the majority of patients.
Physical Therapists for Rehabilitation
Physical therapists aren’t physicians, but they play a central role in sciatica treatment and are often the provider you’ll spend the most time with. A common approach is the McKenzie method, which uses repeated movements in a specific direction to draw referred leg pain back toward the spine, a phenomenon called centralization. Studies show this centralization response occurs in roughly 58% to 91% of people with lower back pain, and among those patients, the majority respond best to extension-based exercises.
A typical McKenzie program involves exercises you perform at home up to 10 times per day, which is a much higher frequency than the one or two supervised sessions per week you’d have in the clinic. The exercises progress from lying flat on your stomach, to propping up on your elbows, to pressing up with your arms while keeping your hips on the surface. If extension movements increase your leg pain rather than reducing it, the therapist will switch to a flexion-based approach instead.
Physiatrists for Complex or Persistent Pain
A physiatrist (a doctor specializing in physical medicine and rehabilitation) bridges the gap between conservative care and surgery. These doctors complete training focused on restoring function without operating, and they have tools your primary care doctor doesn’t. They can perform nerve conduction studies, which use small electrical impulses to pinpoint exactly where along the nerve the problem sits, distinguishing a compressed nerve root from other conditions that mimic sciatica.
Physiatrists also perform spinal injections. Epidural steroid injections deliver anti-inflammatory medication directly to the irritated nerve root and come in three forms depending on how the needle is guided to the spine. A transforaminal injection targets the specific opening where the nerve exits the spine, making it particularly useful when one nerve root is clearly involved. These injections don’t fix the underlying problem, but they can reduce inflammation enough to let you participate more fully in physical therapy and get through the weeks it takes for a disc herniation to heal on its own.
Pain Management Specialists
If your sciatica persists beyond what physiatry and therapy can manage, a pain management specialist offers additional options. These doctors (often anesthesiologists or physiatrists with fellowship training in pain medicine) perform more targeted procedures. A selective nerve root block delivers medication to a single nerve root, which also serves a diagnostic purpose: if the injection eliminates your pain, it confirms which nerve is causing the problem. Medial branch blocks target the small nerves supplying the spinal joints themselves, helpful when facet joint inflammation contributes to your symptoms.
For cases that don’t respond to injections, pain specialists can perform radiofrequency ablation, which uses heat to disrupt the nerve fibers carrying pain signals. Spinal cord stimulation, where a small device delivers electrical pulses to interrupt pain signaling, is reserved for chronic cases that have exhausted other options.
Orthopedic Surgeons and Neurosurgeons
Surgery enters the picture only when conservative treatments have failed to restore your daily function or when nerve compression is causing progressive neurological damage. Two types of surgeons operate on the spine: orthopedic spine surgeons and neurosurgeons. Both complete fellowship training in spine surgery, and for the most common sciatica procedure (a microdiscectomy to remove the portion of disc pressing on the nerve), either is well qualified.
The differences are subtle. Neurosurgeons complete a five- to six-year residency focused on the nervous system and tend to handle more complex cases involving the spinal cord itself, such as tumors within the spinal canal. Orthopedic spine surgeons complete a five-year surgical residency focused on the musculoskeletal system and historically had more training in spinal deformity corrections, though that gap has narrowed. For most sciatica surgeries, the more important question is how often a particular surgeon performs your specific procedure, not which specialty they trained in.
Chiropractors and Osteopathic Doctors
Chiropractors treat sciatica through spinal adjustments, applying targeted pressure or quick thrusts to realign joints and release compressed nerves. This approach can be effective for back-related nerve pain, and many people see a chiropractor as their first point of contact rather than a physician. Chiropractors can’t prescribe medications or order advanced imaging like MRIs, so if your symptoms suggest something beyond a straightforward disc issue, you’ll need a referral to a medical doctor.
Osteopathic physicians (DOs) receive the same medical training as MDs, with additional instruction in musculoskeletal manipulation. They can prescribe medications, order imaging, and perform hands-on spinal manipulation, giving them a broader toolkit. A DO functioning as your primary care doctor can manage the entire conservative treatment phase of sciatica without involving another provider.
When Sciatica Needs Emergency Care
Certain symptoms bypass the usual referral chain entirely and require an emergency room visit. Cauda equina syndrome occurs when the bundle of nerves at the base of the spinal cord becomes severely compressed, and without prompt surgical treatment, the damage can become permanent. The warning signs are numbness in the groin or inner thighs (saddle area), sudden loss of bladder or bowel control, urinary retention, and rapidly worsening weakness in one or both legs. Progressive neurological deficits in the legs, especially when bilateral, are definite red flags that demand immediate evaluation, typically with an urgent MRI and neurosurgical consultation.
Cauda equina syndrome is rare, but the consequences of delay are severe enough that any combination of these symptoms warrants an ER visit rather than waiting for an office appointment.
