Your primary care doctor is the right first stop for sciatica. Most cases improve with conservative treatment over several weeks, and a primary care physician can diagnose the problem, start you on a treatment plan, and refer you to a specialist if your symptoms don’t resolve. Who you see after that depends on how your body responds and whether your pain involves nerve damage, muscle weakness, or a structural problem that needs more targeted care.
Start With Your Primary Care Doctor
A primary care physician can diagnose sciatica through a physical exam and your symptom history. Imaging is usually not necessary at first. During the visit, your doctor will likely perform a straight leg raise test, where you lie on your back while they slowly lift one leg with your knee straight. If this reproduces your familiar shooting pain down the leg, particularly at an angle below 45 degrees, it strongly suggests a compressed nerve root. The test is highly sensitive for disc herniation, meaning it catches most cases, though it can also flag positive in people without disc problems.
Your doctor may also test your reflexes, check for numbness in specific areas of your leg or foot, and ask you to walk on your heels or toes to assess muscle strength. If the exam points to sciatica without any alarming signs, the standard approach is to manage it conservatively for six weeks before ordering any imaging. This typically means anti-inflammatory medications, a muscle relaxant if spasm is contributing to the pain, and a referral to physical therapy. If your pain has a burning or electric quality, your doctor may also try a nerve pain medication.
An MRI becomes appropriate after about six weeks if symptoms haven’t improved with treatment, or sooner if there are red flags like significant leg weakness, unexplained weight loss, or a history of cancer. The American College of Radiology guidelines are clear that uncomplicated sciatica is a self-limited condition and doesn’t warrant imaging early on.
When a Physical Therapist Gets Involved
Physical therapy is one of the most effective tools for sciatica, and your primary care doctor will often write a referral early in the process. The prescription is frequently as simple as “evaluate and treat,” leaving the physical therapist to design the actual program based on how your body moves and responds. You’ll typically attend one or two supervised sessions per week, but the real work happens at home. Many programs ask you to perform specific movements up to 10 times per day, which is a much higher frequency than most people expect.
The focus is on core stabilization, flexibility, and correcting movement patterns that put pressure on the nerve. Low-impact exercise is ideal, especially pool-based work, followed by machine-based exercises. Running and standing with heavy weights should be avoided during recovery. Deep tissue massage and range-of-motion stretching are common additions. The goal is to reduce nerve compression by improving the stability and mechanics of your spine, not just to stretch or strengthen in a general sense.
Physiatrists: The Nonsurgical Spine Specialist
If your sciatica persists despite initial treatment, a physiatrist (a doctor specializing in physical medicine and rehabilitation) is often the next referral. Physiatrists focus entirely on restoring function without surgery. They can perform diagnostic tests like electromyography, which measures electrical activity in your muscles and nerves to pinpoint exactly where compression is occurring and how severe it is.
Physiatrists also perform interventional procedures like epidural steroid injections and nerve blocks, often guided by ultrasound or fluoroscopy for precision. These injections deliver anti-inflammatory medication directly to the irritated nerve root, which can break the pain cycle and allow physical therapy to be more effective. For many people, this combination of targeted injections and rehab resolves sciatica without ever needing surgery.
Neurologists: Diagnosing Complex Nerve Problems
A neurologist specializes in disorders of the nervous system, including the spinal cord and nerve roots. Your doctor may refer you to one if there’s uncertainty about whether the problem originates in the spinal canal or somewhere else, or if your symptoms suggest something beyond a straightforward disc herniation. Neurologists can confirm nerve compression, map out which nerve roots are affected, and distinguish sciatica from other conditions that mimic it, like piriformis syndrome or peripheral neuropathy.
One important distinction: neurologists diagnose sciatica but do not perform surgical treatment. Their role is clarifying the problem and guiding the treatment plan, which may include medications for nerve pain or a referral to a surgeon if the findings warrant it.
Orthopedic Surgeons and Neurosurgeons
Surgery for sciatica is only considered after conservative treatments have failed, typically after three to six months, or when there’s progressive neurological loss like worsening leg weakness or foot drop. Two types of surgeons treat spinal conditions: orthopedic spine surgeons and neurosurgeons. Both can perform the most common procedure for sciatica, a microdiscectomy, which removes the portion of a herniated disc pressing on the nerve. The choice between the two often comes down to your referral network and the surgeon’s individual experience rather than a meaningful difference in training for this specific procedure.
Most people referred for a surgical consultation don’t end up needing surgery. The consultation itself is valuable because spine surgeons see high volumes of sciatica and can give you a clear picture of whether your imaging findings match your symptoms and what your realistic recovery timeline looks like.
Symptoms That Need Emergency Care
Certain symptoms require an emergency room visit, not a scheduled appointment. Cauda equina syndrome occurs when the bundle of nerves at the base of the spinal cord becomes severely compressed, and it can cause permanent damage if not treated within hours. Go to the ER if you experience any of the following alongside your sciatica: loss of bladder or bowel control, numbness in the groin or inner thighs (called saddle anesthesia), or sudden weakness in both legs. Sexual dysfunction that appears alongside these symptoms is another warning sign. This is rare, but it is a true surgical emergency.
Choosing the Right Path
The typical progression looks like this: primary care doctor first, physical therapy started early, and then a specialist referral only if you’re not improving after six to eight weeks. If your pain is manageable and you have no weakness or numbness, there’s no need to jump straight to a specialist. If you’re dealing with significant nerve symptoms like a foot that slaps when you walk or a patch of skin that’s gone numb, ask your primary care doctor for an earlier referral to a physiatrist or neurologist. The vast majority of sciatica resolves without surgery, but getting the right type of doctor involved at the right time makes recovery faster and less frustrating.
