For most lower back pain, your primary care doctor is the right first step. The majority of cases don’t require a specialist, and a general practitioner can diagnose the problem, rule out anything serious, and start treatment. From there, you may be referred to a specialist depending on what’s causing the pain, how long it’s lasted, and whether it involves your nerves, joints, or spine structure.
Start With Your Primary Care Doctor
A primary care physician will take a focused history and perform a physical exam to identify whether your pain has a specific cause or whether it falls into the most common category: nonspecific low back pain. Most people with lower back pain don’t need imaging right away. X-rays and MRIs are only indicated when your doctor suspects a specific structural problem and early diagnosis would change your treatment.
For straightforward cases, your doctor will likely reassure you that serious underlying disease is unlikely and recommend staying active. Nondrug options are preferred as first-line treatment: heat, gentle movement, and possibly massage or spinal manipulation. If medication is needed, anti-inflammatory drugs like ibuprofen or naproxen are the go-to choice endorsed by major clinical guidelines. Patients who don’t improve with these initial steps are the ones who get referred to specialists.
When a Physiatrist Makes Sense
A physiatrist (a doctor specializing in physical medicine and rehabilitation) is one of the most useful specialists for persistent back pain that hasn’t responded to basic treatment but doesn’t clearly need surgery. Physiatrists perform a thorough musculoskeletal and neurological exam, and they can order imaging, blood work, or nerve conduction studies to pin down a diagnosis.
What sets them apart is their range of treatment options. They coordinate physical therapy to correct posture, improve workplace ergonomics, and strengthen the muscles that stabilize your lower back. For people with severe or stubborn pain, physiatrists trained in spinal procedures can offer targeted injections, each designed for a different pain source. They bridge the gap between “take ibuprofen and wait” and “you need surgery,” which is where most back pain patients actually live.
Physical Therapy and Chiropractic Care
Both physical therapists and chiropractors treat lower back pain, but their approaches differ. Physical therapy focuses on corrective exercises, posture training, and strengthening. It also tends to reduce the need for further interventions like imaging, injections, and prescription medication down the line. Chiropractic care relies more heavily on spinal manipulation and typically incorporates imaging as part of the initial assessment.
In terms of time commitment, the two are comparable. Over a four-week treatment period, chiropractic patients averaged about 5 sessions while physical therapy patients averaged about 6. Your primary care doctor or physiatrist can help you decide which approach fits your specific problem. Many people with nonspecific lower back pain do well with either one.
Pain Management Specialists
If your pain is chronic and conservative treatments haven’t provided enough relief, a pain management specialist (often an anesthesiologist or physiatrist with additional training) can offer interventional procedures. These go beyond oral medication to target pain at its source:
- Epidural steroid injections deliver anti-inflammatory medication directly into the spinal canal to reduce nerve irritation.
- Facet joint injections block pain from the small joints connecting each vertebra.
- Nerve blocks interrupt pain signals from a specific nerve using an anesthetic.
- Radiofrequency ablation uses heat from radio waves to disrupt a nerve’s ability to transmit pain, providing longer-lasting relief.
- Sacroiliac joint injections target the joint where the spine meets the pelvis, a common but often overlooked source of lower back pain.
These procedures are typically guided by imaging so the needle reaches the exact right spot. They’re not permanent fixes in every case, but they can provide months of relief and help you participate more fully in physical therapy.
When You Might Need a Neurologist
If your lower back pain comes with numbness, tingling, or muscle weakness in your legs, a neurologist can help determine whether a nerve is being compressed or damaged. The key diagnostic tool here is electromyography (EMG), usually performed alongside a nerve conduction study. These tests measure the electrical activity in your muscles and how well your nerves are transmitting signals.
An EMG can help diagnose conditions like sciatica, pinched nerves, and radiculopathy (nerve root compression where nerves exit the spinal column). If you’re experiencing shooting pain down one leg, foot drop, or progressive weakness, these tests help clarify exactly which nerve is involved and how severe the damage is.
When a Surgeon Gets Involved
Surgery is typically the last option, reserved for people with clear structural problems that haven’t improved with months of conservative care. Two types of surgeons operate on the spine: orthopedic surgeons and neurosurgeons.
Orthopedic surgeons focus on the musculoskeletal system, including bones, ligaments, and joints. They’re the typical choice for herniated discs, spinal deformities, arthritis-related changes, and spinal injuries. Neurosurgeons specialize in the nervous system and tend to handle conditions involving tumors, vascular problems, and complex nerve-related issues. In practice, there’s significant overlap, and both perform common procedures like disc surgery and spinal fusion.
For herniated discs specifically, surgery provides faster early relief. At six weeks, 48% of surgical patients reported a 50% or greater reduction in pain, compared to 17% of those treated conservatively. By 12 weeks, the gap narrows: 35% surgical versus 24% conservative. And by two years, outcomes are nearly identical, with 44% of surgical patients and 49% of conservative patients reporting that level of improvement. This means surgery accelerates recovery but doesn’t necessarily change where you end up long-term, which is why most doctors exhaust non-surgical options first.
Signs That Point to a Rheumatologist
Not all lower back pain is mechanical. If your pain started gradually before age 40, is worse in the morning, improves with movement rather than rest, and has lasted more than three months, you may have inflammatory back pain. This pattern can signal conditions like ankylosing spondylitis, a type of arthritis that primarily affects the spine.
Your primary care doctor can refer you to a rheumatologist, who specializes in inflammatory and autoimmune conditions. Diagnosis involves a combination of physical examination (checking posture, flexibility, and chest expansion), imaging, and blood tests that look for markers of inflammation. An MRI can detect early-stage disease before changes show up on X-rays. Blood testing for a gene called HLA-B27 can support the diagnosis, though having the gene doesn’t guarantee the condition, and lacking it doesn’t rule it out. Most people with inflammatory spinal conditions are managed with medication and exercise rather than surgery.
When to Go to the Emergency Room
Most lower back pain doesn’t require emergency care, but a few situations do. Go to the ER if your back pain follows a traumatic injury like a car accident, a serious fall, or a sports collision. Also seek emergency care if your pain comes with new loss of bowel or bladder control, or if it’s accompanied by a fever. These combinations can signal spinal cord compression or infection, both of which need immediate evaluation.
