For most people, a primary care physician is the right first stop for lower back pain. The vast majority of lower back pain stems from muscle or bone issues that resolve with conservative treatment, and a primary care doctor can assess your symptoms, rule out serious causes, and refer you to a specialist if needed. That said, certain symptoms and timelines call for specific types of specialists, and knowing who does what can save you weeks of frustration.
Start With Your Primary Care Doctor
A primary care physician will perform a physical exam that includes inspecting your posture, pressing on specific areas of your spine, running provocative tests to reproduce your pain, and checking your neurological function (reflexes, sensation, and strength in your legs). When the neurological exam comes back normal, imaging like an MRI is often unnecessary, and treatment focuses on practical steps: ergonomic adjustments, exercise modification, physical therapy, and occasional use of anti-inflammatory medications.
This initial visit also serves a critical screening purpose. Lower back pain can occasionally be caused by conditions that have nothing to do with your spine, including kidney stones, abdominal aortic aneurysm, gastrointestinal disease, and pelvic infections. Your primary care doctor is trained to catch these mimickers before sending you down the wrong treatment path.
Back pain is classified by how long it lasts: acute (under four weeks), subacute (four to twelve weeks), and chronic (longer than twelve weeks). For acute and subacute pain, the American College of Physicians recommends starting with non-drug treatments like heat therapy, massage, acupuncture, or spinal manipulation. If medication is needed, anti-inflammatory drugs or muscle relaxants are first-line options. Notably, acetaminophen (Tylenol) has not been shown to be more effective than placebo for back pain, and oral steroids don’t help either.
When Physical Therapy Makes Sense
Physical therapists are often involved early in back pain treatment, and in most U.S. states you can see one without a doctor’s referral. In California, for example, patients can start physical therapy directly for up to 45 days or 12 visits without a physician’s diagnosis. After that, a doctor needs to sign off on the treatment plan. Rules vary by state, but direct access has become the norm rather than the exception.
For chronic back pain, exercise-based approaches have some of the strongest evidence behind them. The ACP guidelines list exercise, yoga, tai chi, spinal manipulation, cognitive behavioral therapy, mindfulness-based stress reduction, and progressive relaxation as recommended first-line treatments before trying medications. A physical therapist can guide you through many of these approaches in a structured program.
Physiatrists for Persistent or Complex Pain
A physiatrist (physical medicine and rehabilitation specialist) is worth considering when back pain isn’t resolving with basic treatment or when it’s affecting your ability to work, exercise, or handle daily tasks. Physiatrists take a functional approach, meaning they evaluate how your whole body moves and look at physical, psychological, and social factors contributing to your pain.
Treatment through a physiatrist typically moves through three stages. The acute stage focuses on reducing pain through relative rest, medications, and gentle range-of-motion exercises. The recovery stage builds strength and flexibility. The functional stage targets return to specific activities, whether that’s your job, a sport, or simply being able to pick up your kids without wincing. Aquatic therapy, biofeedback to reduce muscle tension, and vocational rehabilitation for workplace modifications are all tools in their toolkit. If you need injections like targeted nerve root blocks or want a comprehensive rehab plan without surgery, a physiatrist is often the right specialist.
Pain Management Specialists
Interventional pain management doctors focus specifically on procedures that interrupt or reduce pain signals. If your pain hasn’t responded to physical therapy, medications, and time, these specialists offer options like targeted cortisone injections around specific nerve roots, radiofrequency treatments that deactivate pain-transmitting nerve fibers, spinal cord stimulators that use low-voltage electrical pulses to block pain, and implantable pumps that deliver medication directly into the spinal fluid.
These procedures are typically reserved for people with chronic pain who’ve exhausted more conservative options. Your primary care doctor or physiatrist will usually make this referral when the time is right.
When You Need a Neurologist
A neurologist becomes important when your back pain comes with signs of nerve involvement: tingling, numbness, weakness, muscle spasms, or pain radiating down your legs. Neurologists can order specialized tests that measure how well your nerves and muscles are functioning. These electrical tests can pinpoint whether a herniated disc is pressing on a specific nerve, which helps determine the best treatment approach. If you’re experiencing progressive weakness in one or both legs, a neurologist should be part of your care team.
Surgeons: Orthopedic vs. Neurosurgeon
Surgical consultation is reserved for specific structural problems that haven’t improved with at least six weeks of conservative care. The American College of Radiology recommends imaging only after that six-week window in most cases, or sooner if red flags are present. So if you’re in week two of a sore back, a surgeon’s office is almost certainly premature.
When surgery is on the table, both orthopedic spine surgeons and neurosurgeons perform spinal procedures, and there’s significant overlap in what they treat. The key differences: neurosurgeons tend to specialize in complex procedures involving the spinal cord itself, such as tumors within the spinal canal or severe cervical stenosis compressing the cord. Orthopedic spine surgeons have traditionally had more training in spinal deformity corrections like scoliosis. For common procedures like disc surgery or spinal fusion, either type of surgeon can be well qualified. What matters more than the title is the surgeon’s specific experience with your condition.
Rheumatologists for Inflammatory Back Pain
Most back pain is mechanical, meaning it comes from muscles, joints, or discs and gets worse with movement. Inflammatory back pain behaves differently, and that difference is your clue to see a rheumatologist. If your lower back or buttock pain came on gradually, feels worst in the morning or after sitting still, wakes you up at night, and actually improves with movement or exercise, you may be dealing with an inflammatory condition like ankylosing spondylitis.
Ankylosing spondylitis primarily affects the joints where the base of the spine meets the pelvis and the vertebrae of the lower back. It can also cause symptoms that seem unrelated to your back: eye pain or vision changes, skin rashes, and stomach pain. The pattern of stiffness improving with activity rather than rest is the hallmark that separates it from a muscle strain or disc problem. Early diagnosis matters because targeted treatment can slow the disease’s progression.
Symptoms That Need Emergency Care
A small number of back pain cases require immediate attention. Cauda equina syndrome occurs when the bundle of nerves at the base of the spinal cord becomes severely compressed, and treatment within 48 hours significantly improves outcomes for bladder, bowel, and leg function. Go to the emergency room if you experience any combination of these symptoms alongside back pain:
- Urinary retention: your bladder feels full but you can’t feel the urge to urinate or can’t go
- Loss of bowel or bladder control
- Saddle numbness: loss of sensation in the groin, buttocks, or inner thighs
- Progressive weakness or paralysis in one or both legs
Other red flags that warrant urgent evaluation include back pain with unexplained weight loss, a history of cancer, fever suggesting infection, or pain after significant trauma. In these scenarios, imaging is appropriate immediately rather than waiting the standard six weeks.
A Practical Path Forward
For the majority of people with new lower back pain, the path looks like this: see your primary care doctor (or go directly to a physical therapist if your state allows it), try conservative treatment for four to six weeks, and get a specialist referral only if things aren’t improving. Chronic pain that has lasted more than twelve weeks with an inadequate response to non-drug therapy may warrant anti-inflammatory medications as a next step, with other prescription options as second-line choices. Opioids are considered only after all other approaches have failed, and only when the potential benefits outweigh the risks for your specific situation.
The specialist you eventually need, if you need one at all, depends entirely on what’s causing the pain. Nerve symptoms point toward a neurologist or physiatrist. Morning stiffness that improves with movement points toward a rheumatologist. Structural problems confirmed on imaging after failed conservative care point toward a surgeon. And persistent pain that’s affecting your quality of life but doesn’t need surgery points toward a pain management specialist or physiatrist. Your primary care doctor’s job is to figure out which of these paths fits your situation.
