Your primary care doctor is the right starting point for sciatica. They can diagnose the condition, prescribe initial treatments, and refer you to a specialist if your pain doesn’t improve within six to eight weeks. Beyond that window, the type of specialist you need depends on whether your sciatica calls for injections, rehabilitation, or surgery.
Start With Your Primary Care Doctor
A primary care physician can diagnose sciatica through a physical exam without any imaging in most cases. They’ll perform a straight leg raise test, where you lie on your back while they lift your affected leg to see if it reproduces the shooting pain. They’ll also check muscle strength in your thigh, hamstrings, and foot, test your reflexes, and compare both sides to gauge how the nerve is functioning.
From there, your doctor will typically start with conservative treatment: a physical therapy program focused on core strengthening and flexibility, anti-inflammatory medications like ibuprofen or naproxen, and possibly a muscle relaxant or nerve pain medication if the inflammation alone isn’t the main driver. They may try several anti-inflammatory options in succession to find the one that works best for you. Most sciatica improves with this approach. A one-year follow-up study of patients with disc-related sciatica found recovery rates of 95% regardless of whether patients were treated conservatively or surgically.
Imaging like an MRI is generally not recommended until you’ve had at least six weeks of treatment without meaningful improvement. At that point, your doctor will likely order imaging and refer you to a specialist.
Physiatrists: The Non-Surgical Specialists
A physiatrist (pronounced fiz-EYE-uh-trist) specializes in physical medicine and rehabilitation. If your sciatica isn’t resolving but doesn’t clearly need surgery, this is often the most useful specialist to see. Physiatrists bridge the gap between conservative care and the operating room.
They can run electrodiagnostic tests that measure how well your nerves and muscles are functioning, which helps pinpoint exactly where the nerve is being compressed. They also perform epidural steroid injections, which deliver anti-inflammatory medication directly to the irritated nerve root. These injections have been used for over 50 years and can be administered through several routes: between the vertebrae, through the tailbone area, or through the nerve’s exit point in the spine. The approach your physiatrist chooses depends on where the compression is happening. Beyond injections, physiatrists coordinate rehabilitation programs, prescribe orthotics, and manage your care without surgery.
Pain Management Specialists
Pain management doctors overlap significantly with physiatrists, and some are physiatrists by training. Others come from anesthesiology backgrounds. Their focus is on interventional procedures for pain that hasn’t responded to physical therapy and oral medications. For sciatica specifically, they perform epidural steroid injections, nerve blocks, and procedures like radiofrequency ablation, which uses heat to disrupt pain signals from a specific nerve. If your sciatica is chronic and you’re not a candidate for surgery, a pain management specialist can help you manage symptoms long-term.
Orthopedic Surgeons and Neurosurgeons
These are the two types of surgeons who operate on sciatica, and their training overlaps more than most people realize. Orthopedic surgeons specialize in the skeletal system, so they’re a natural fit when sciatica stems from structural spine problems like a herniated disc or spinal stenosis. Neurosurgeons specialize in the nervous system and focus on the nerve damage itself. Both can perform the same spinal surgeries for sciatica, including microdiscectomy (removing the portion of a disc pressing on the nerve).
Referral to a surgeon is appropriate when pain hasn’t responded to six to eight weeks of conservative care, or when pain is so severe that even strong medications can’t control it. Surgery tends to produce faster relief. In one major study, 69% of surgically treated patients reported success at 12 months compared to 48% of those treated without surgery. Surgically treated patients also had significantly better leg pain outcomes at one year. That said, both groups often converge in long-term results for back pain and overall physical function.
Physical Therapists
Physical therapists aren’t doctors, but they play a central role in sciatica treatment at nearly every stage. Core strengthening and spinal stabilization exercises are considered the foundation of sciatica recovery, and a physical therapist designs and supervises that program. They use hands-on techniques to reduce stiffness around the sciatic nerve and prescribe exercises to build flexibility in your back, core, and legs. In many states, you can see a physical therapist through direct access without a doctor’s referral, which means you can start treatment quickly. Even if you eventually need injections or surgery, physical therapy is almost always part of the recovery plan.
When to Go to the Emergency Room
Most sciatica is painful but not dangerous. There is one exception: cauda equina syndrome, where the bundle of nerves at the base of the spinal cord becomes severely compressed. This is a medical emergency. The red flags include numbness or loss of sensation in the groin and inner thigh area, loss of bladder or bowel control, and progressive weakness in both legs. If you develop any of these symptoms alongside your sciatica, go to the emergency room. Delays in treatment can lead to permanent nerve damage.
Choosing the Right Path
For most people, the sequence looks like this: see your primary care doctor first, start physical therapy and medication, and give it six to eight weeks. If you’re improving, stay the course. If not, your doctor will refer you to a physiatrist or pain management specialist for injections and advanced diagnostics. Surgery enters the conversation only when conservative treatments and injections haven’t worked, or when nerve damage is progressing.
If you already know your sciatica is severe, you’ve had it before, or you have a known disc herniation from prior imaging, it’s reasonable to ask your primary care doctor for an earlier referral. You don’t necessarily need to wait the full six to eight weeks if your symptoms are clearly worsening or if you’re unable to work or sleep because of the pain.
