Back Pain FAQs: What Every Patient Should Know

By H. Rand Scott, MD — Medical Director, Newport Pain Management Reviewed and updated August 2026

The back is one of the most complex mechanical structures in the body — 24 vertebrae, dozens of discs and joints, hundreds of ligaments and muscles, and the entire spinal cord running through the middle of it. It's also one of the most common sources of pain in modern life. This FAQ covers what causes back pain, when it needs medical attention, what testing is genuinely useful (and what isn't), and the full range of treatments — from home care through modern interventional procedures.

The backbone isn't one long bone. It's a stack of 24 separate vertebrae, arranged like a stack of blocks with rubbery cartilage discs between them acting as shock absorbers. Small paired joints called facet joints link each vertebra to the ones above and below, and allow the spine to bend and twist. The spinal cord runs through a canal in the vertebrae — a piece of string running through a beaded necklace. In the lower back, the spinal cord itself ends and the canal contains a bundle of nerves called the cauda equina.

Muscles, tendons, and ligaments support the whole structure and let it move. Any part of this system can generate pain — the muscles, the discs, the facet joints, the ligaments, the nerve roots leaving the spine, or the joints where the spine meets the pelvis (the sacroiliac joints).

Most acute back pain comes from muscle or ligament strain, minor disc issues, or facet joint irritation. Emotional stress worsens all of these and slows recovery. Beyond common strains and sprains, specific causes include:

• Ruptured or herniated disc — a disc bulges into the spinal canal and presses on a nerve root, often producing pain radiating down one leg (sciatica) or arm.
• Spinal stenosis — narrowing of the spinal canal that squeezes nerves. Classic pattern: pain and heaviness in the legs that gets worse walking and better when sitting or bending forward.
• Facet joint arthritis — degeneration in the small joints between vertebrae, a common cause of chronic axial low back pain, particularly in older adults.
• Sacroiliac joint dysfunction — the joint between the base of the spine and the pelvis. A commonly under-recognized cause of low back and buttock pain.
• Osteoarthritis of the spine (spondylosis).
• Ankylosing spondylitis and other inflammatory arthritides.
• Osteoporotic compression fracture — brittle vertebrae can fracture with minor stress in older adults, particularly women with untreated osteoporosis.
• Fibromyalgia and other chronic pain syndromes.
• Referred pain from organs — kidney stones, kidney infection, prostate problems, gynecologic conditions, aortic aneurysm, and diseases of the intestines or pancreas can all present as back pain.
• Serious but less common causes — spinal infection, tumor, or metastasis. These are uncommon but must be considered when specific warning signs are present.

A herniated disc most commonly produces pain that radiates down one leg (sciatica) or arm — often more severe than the back pain itself. Symptoms sometimes include numbness or weakness in specific muscle groups. Most disc herniations resolve without surgery over weeks to a few months. When symptoms persist or when there is significant weakness, MRI is the imaging study of choice.

In spinal stenosis, degenerative changes narrow the spinal canal and compress the nerves inside it. The classic pattern — leg pain and heaviness that worsens with walking and improves with sitting or leaning forward — is called neurogenic claudication. Stenosis is common in older adults and can often be managed for years with a combination of activity modification, targeted physical therapy, and epidural steroid injections. When function is significantly compromised, surgical decompression is highly effective.

Osteoporotic vertebral bones can break under stress that would be trivial for normal bone. A vertebral compression fracture can happen with a fall, a heavy lift, or even ordinary bending. Modern treatment is much better than it once was: minimally invasive procedures — vertebroplasty and kyphoplasty — inject bone cement into the fractured vertebra, often providing significant pain relief and improving function within days. Long-term treatment of the underlying osteoporosis is essential to prevent additional fractures.

Because the abdominal and pelvic organs share nerve territory with the back, several serious conditions can present as back pain:

• Kidney stones and kidney infections.
• Aortic aneurysm — particularly important in older adults and smokers.
• Pancreatitis.
• Ovarian or uterine conditions.
• Prostate infection.
• Cancer metastatic to the spine — most commonly from breast, lung, prostate, or kidney primary.
• Multiple myeloma.

The evaluation of back pain always includes checking that the pain isn't actually coming from somewhere else.

Physicians classify back pain by duration:

• Acute — less than 6 weeks. About 80% of back pain episodes fit this category.
• Subacute — 6 to 12 weeks.
• Chronic — more than 12 weeks. About 5–10% of back pain episodes become chronic.

The treatment approach differs substantially between these categories. Acute pain is usually best managed conservatively with the expectation of recovery. Chronic pain calls for careful diagnostic work to identify the specific pain generator and a multimodal treatment plan.

Most back pain resolves on its own within a few weeks. Contact your doctor if you have back pain accompanied by any of the following:

• Weakness or numbness in one or both legs.
• Pain radiating below the knee.
• Back pain following a fall or significant injury.
• Back pain with fever.
• Pain that continues to disrupt sleep after several nights.
• Pain that hasn't improved with home treatment after 4–6 weeks.
• Pain worse when lying down.
• A history of cancer.
• Unexplained weight loss.
• Age over 60 with new-onset pain, or age under 20.

Seek same-day medical evaluation if you have:

• Loss of bowel or bladder control.
• Numbness in the groin or saddle area.
• Progressive weakness in the legs.
• Fever with severe back pain.

That last cluster can represent cauda equina syndrome (surgical emergency), spinal infection, or another condition where delay in treatment can produce permanent damage.

The history and physical exam are the most important parts of a back pain evaluation. Expect questions about:

• Location and character of the pain — where exactly, is it aching, sharp, burning, shooting?
• What brings the pain on and what relieves it.
• Whether the pain radiates and where.
• Duration and course — sudden onset or gradual, better or worse over time.
• Any triggering event.
• Home treatments tried and their effect.
• Associated symptoms — weakness, numbness, bowel/bladder change, fever, weight loss.
• Occupation and daily activities.
• Other medical conditions and medications.

The physical exam includes observation of posture and gait, range of motion, palpation to localize tenderness, tests of muscle strength and reflexes, and — when indicated — specific provocative maneuvers to test the discs, facet joints, sacroiliac joints, and nerve roots.

For most acute back pain, imaging in the first several weeks doesn't improve outcomes. Studies consistently show that early imaging in uncomplicated acute back pain leads to more procedures without better function or less pain. Nearly everyone over 40 has some degenerative findings on MRI, and pursuing incidental findings can lead down unhelpful paths.

Imaging is appropriate when:

• Warning signs suggest a specific serious condition (fracture, tumor, infection, cauda equina).
• Pain persists despite reasonable conservative treatment (usually 6 weeks or more).
• A specific procedure is being planned.
• Neurologic deficits are present.

When imaging is needed:

• X-ray — useful for suspected fracture, alignment problems, and some arthritic changes.
• MRI — the study of choice for discs, nerve roots, spinal cord, tumor, and infection. Doesn't use radiation. Cannot be performed with certain implanted metal devices.
• CT scan — useful for bone detail and when MRI is contraindicated. Uses ionizing radiation.
• Bone scan — reserved for specific questions such as suspected metastatic disease, occult fracture, or infection.
• EMG and nerve conduction studies — help confirm nerve root compression and distinguish spinal nerve problems from more peripheral nerve entrapment.

Myelography — an older test using contrast dye injected into the spinal canal — has largely been replaced by MRI and is rarely needed today. Blood tests are useful only when there's a specific reason to suspect infection, inflammatory arthritis, or metabolic bone disease.

For pain that isn't resolving, identifying the specific pain generator matters. Modern evaluation of persistent back pain often includes diagnostic nerve blocks — small, targeted injections of local anesthetic that can confirm whether a specific structure (a nerve root, a facet joint, the sacroiliac joint, a disc) is the source of pain. This diagnostic step is often what makes effective long-term treatment possible.

Excellent for most people. Roughly 85–90% of acute back pain episodes improve substantially within one to two months with conservative treatment. The minority whose pain becomes chronic is where modern interventional pain management can make the biggest difference — targeted diagnosis and treatment often produce significant relief for patients whose pain seemed intractable with generic approaches.

Treatment ranges across a wide spectrum, and modern care usually starts with the least invasive appropriate option and escalates only as needed.

Current evidence-based guidance for acute back pain:

• Stay active. Prolonged bed rest actually slows recovery from most acute back pain. Limit bed rest to a day or two at most, and only if pain is severe. Ordinary daily activity, modified to avoid what clearly aggravates the pain, is better than lying down.
• Return to regular activity gradually as pain permits — don't wait for it to fully resolve.
• Heat or cold: use whichever feels better. Heat relaxes tight muscles; cold numbs and reduces inflammation. Don't apply either to the point of skin damage.
• Gentle walking and stretching as soon as tolerated typically accelerates recovery.
• Over-the-counter analgesics (acetaminophen, ibuprofen, naproxen) can provide meaningful relief. Follow package directions or your doctor's guidance.

Once acute pain has settled enough to allow it, a targeted exercise program is one of the most effective long-term treatments for back pain. Effective programs typically include:

• Core strengthening — the deep abdominal and back muscles that stabilize the spine.
• Stretching to restore range of motion.
• Aerobic exercise (walking, swimming, cycling, elliptical) to improve overall conditioning and reduce recurrence risk.
• Postural training and body mechanics education.

A physical therapist can tailor a program to your specific pattern of pain and dysfunction. Don't push through exercises that clearly make the pain worse — that's a signal to modify, not to persist.

Small changes in daily habits accumulate:

• When sitting: firm chair, upper back straight, feet flat on the floor, knees roughly level with hips. Use a small lumbar support to maintain the natural curve of the lower back. Stand and stretch every 30–45 minutes.
• When standing: weight even on both feet, knees unlocked. If standing for long periods, rest one foot on a low stool and switch periodically.
• When sleeping: firm mattress. Side sleeping with knees slightly bent and a pillow between the knees is well-tolerated by most people with back pain. Avoid stomach sleeping.
• When lifting: bend at the knees and hips, keep the load close to the body, and lift with the legs. Move your feet rather than twisting the torso when carrying a load. Get help for loads that are too heavy.
• Cushioned shoes provide meaningful shock absorption; high heels tend to shift posture in ways that stress the low back.
• Maintain a healthy body weight. Excess weight — particularly abdominal — increases the load on the lumbar spine and is one of the more modifiable risk factors for recurrent back pain.

Stress makes back pain worse, and back pain increases stress. The mechanism is not mysterious: stress increases muscle tension, disrupts sleep, and lowers pain tolerance. Effective stress management — whether through exercise, cognitive-behavioral techniques, relaxation training, or professional support — is part of chronic back pain treatment, not an optional add-on.

Common medication categories for back pain:

• Acetaminophen — modest but real benefit for many patients; low side-effect profile.
• NSAIDs (ibuprofen, naproxen, celecoxib) — the most consistently effective first-line medication class for musculoskeletal back pain. Long-term use carries gastrointestinal, kidney, and cardiovascular considerations.
• Muscle relaxants (cyclobenzaprine, methocarbamol, tizanidine) — useful short-term for acute muscle spasm. Not recommended for long-term use.
• Gabapentin and pregabalin — effective for the radicular (nerve-root) component of back pain.
• Certain antidepressants (duloxetine, tricyclics) — evidence-based for chronic musculoskeletal pain at pain-effective doses, independent of any mood effect.
• Topical treatments (diclofenac gel, lidocaine patches) — useful adjunct with low systemic side-effect profile.
• Opioids — have a limited role in chronic non-cancer back pain. They can be appropriate short-term for severe acute pain, but long-term use is generally not recommended given the balance of modest long-term benefit against significant risks.

For back pain that hasn't resolved with conservative care, modern interventional pain management offers a range of targeted treatments — most of them outpatient procedures under image guidance that address specific pain generators identified during evaluation.

Epidural steroid injection. The most established interventional treatment for radicular (nerve-root) back pain — pain radiating down a leg or arm from a compressed nerve root. Steroid medication is injected around the affected nerve root under X-ray or fluoroscopic guidance. Can provide significant relief and often speeds recovery from acute radiculopathy.

Medial branch block and radiofrequency ablation. For pain arising from arthritic facet joints, diagnostic medial branch blocks first confirm the facet joints are the pain source. When confirmed, radiofrequency ablation (RFA) uses a needle-electrode to deliver heat to the small nerves supplying the facet joints, disrupting their ability to transmit pain. Relief typically lasts 6–12 months and the procedure can be repeated.

Sacroiliac joint injection and RFA. For sacroiliac joint dysfunction, targeted injections and, in appropriate cases, RFA of the nerves supplying the joint can provide significant relief.

Spinal cord stimulation. For chronic back and leg pain that has not responded to other treatments — particularly failed back surgery syndrome — spinal cord stimulation uses a small implanted device to interrupt pain signals before they reach the brain. Modern SCS systems have expanded significantly in effectiveness over the past decade.

Vertebroplasty and kyphoplasty. For acute painful vertebral compression fractures — usually from osteoporosis — these minimally invasive procedures inject bone cement into the fractured vertebra. Pain relief is often significant and can happen within days.

Intrathecal drug delivery. For severe refractory pain, medications delivered directly into the spinal canal via an implanted pump can provide relief that oral medications cannot.

Most back pain never requires surgery. Surgery is generally considered when there is:

• A herniated disc with significant leg weakness or a worsening neurologic deficit.
• Spinal stenosis with substantial functional impairment.
• Cauda equina syndrome (surgical emergency).
• Spinal instability from fracture, tumor, or infection.
• Severe, disabling pain that has not responded to a full course of non-operative treatment including appropriate interventional pain procedures.

For most acute back pain, a stepwise approach — conservative care first, targeted interventional pain procedures when needed — produces good outcomes without surgery.

• What is this medication supposed to do, and how long before I notice results?
• What is the name — brand and generic — and are they interchangeable?
• What side effects should I watch for?
• How and when should I take it (with food, on an empty stomach, at a specific time of day)?
• What should I do if I miss a dose?
• Are there any medications or supplements I should avoid taking at the same time?
• How long am I expected to be on this?

Bring a current list of all medications and supplements to every appointment. Some pain medications interact meaningfully with other common drugs.

Most back pain resolves. Of the fraction that doesn't, modern interventional pain management can identify the specific pain generator and target treatment accordingly — often producing significant relief without surgery. The key steps: recognize the warning signs that call for prompt medical evaluation, stay active during acute episodes rather than resorting to bed rest, and see a pain specialist if pain has not resolved by six to twelve weeks despite reasonable treatment.
