Back Pain: Causes, Relief, and When to See a Doctor
Back pain is any ache, stiffness, soreness, or sharp pain felt anywhere along your spine, most often in the lower back. It is one of the most common reasons people see a doctor, and most cases clear up on their own within a few weeks. This page explains what back pain feels like, the conditions that cause it, the warning signs that need urgent care, what you can do for relief, and when to see a specialist near you.

What Back Pain Feels Like
Back pain shows up in many ways, and the way yours feels can offer clues about what is going on. Some people describe a dull, constant ache low in the back that gets worse after sitting or standing too long. Others feel a sudden sharp or stabbing pain that hits during a lift or a twist. A tight, knotted feeling across the muscles is also common, especially after a hard workout or a day of yard work.
Doctors often group back pain by where it sits. A sore lower back (the lumbar region, just above the hips) is by far the most common spot, since it carries most of your body weight. A sore upper back between the shoulder blades, sometimes called rhomboid or upper back muscle pain, is often tied to posture, desk work, or carrying heavy bags. Middle back pain is less common and can come from the spine or the muscles along it. Pain over the sacrum, the triangle-shaped bone at the base of the spine, can come from the joints that connect your spine to your pelvis.
Doctors also describe back pain by how long it lasts. Acute pain comes on suddenly and usually clears within a few weeks. Chronic back pain lasts longer than three months and may need a closer look. Pain that travels down one leg, tingles, or feels like an electric shock points toward a pinched nerve rather than a simple muscle problem.

Common Causes of Back Pain
Most back pain comes from the muscles, ligaments, joints, discs, or nerves of the spine. Here are the most common ones.
Muscle and ligament problems
- Sprains and strains are the number one cause. A strain is an overstretched or torn muscle or tendon; a sprain involves a ligament. Lifting something heavy, twisting awkwardly, or a sudden movement can trigger a muscle tear or a lumbar strain that leaves the area sore and stiff.
- A back spasm is when a muscle tightens hard and will not let go. It often follows a strain and can be intense for a day or two.
Disc and nerve problems
- A herniated disc happens when the soft cushion between two spine bones bulges and presses on a nearby nerve. This is a frequent cause of pain that shoots into the buttock or leg.
- Sciatica is pain that travels along the sciatic nerve, from the lower back down through the hip and leg, often from a herniated disc or nerve entrapment.
Joint, bone, and wear-and-tear problems
- Osteoarthritis and broader arthritis wear down the joints of the spine over time, causing stiffness and an ache that is often worse in the morning.
- Bone spurs are bony growths that can narrow the space around nerves.
- Osteoporosis thins the bones and can lead to a small spine fracture that causes sudden back pain, sometimes from very little force.
- Stress fractures from repeated strain can also cause lasting pain.
Inflammatory and rarer causes
- Ankylosing spondylitis is a form of inflammatory arthritis of the spine that often starts as stiffness in younger adults.
- Rheumatoid arthritis can affect the joints of the neck and back.
- Less common but serious causes include osteomyelitis (a bone infection), bone cancer, and sarcoma. These are rare, but they are part of why pain that will not improve deserves a medical exam.
Pregnancy is another common reason for back pain. The added weight and shifting posture put extra load on the lower back, and this kind of pain usually eases after delivery.
When to Seek Emergency or Urgent Care
Most back pain is not dangerous, but a few warning signs mean you should not wait. Get emergency or urgent care right away if you have any of these.
Call 911 or go to the emergency room if you have:
- Loss of control over your bladder or bowels, or numbness around the groin, buttocks, or inner thighs. This can signal a serious nerve emergency called cauda equina syndrome.
- New weakness in one or both legs, or trouble walking.
- Back pain after a car crash, a hard fall, or another major injury.
- Severe pain with a fever, chills, or a warm, swollen area on the back, which can point to an infection.
See a doctor the same day or within a day or two if you have:
- Back pain with unexplained weight loss or a history of cancer.
- Pain that is severe, steady, and does not ease at all with rest or position changes.
- Pain that keeps you up at night or is clearly getting worse over days.
- Numbness, tingling, or weakness that is spreading.
If you are over 50, have osteoporosis, take steroids long term, or have a weakened immune system, get checked sooner rather than later. These factors raise the chance of a fracture or infection. When in doubt, call your doctor or a nurse line and describe what you are feeling.
How to Get Relief and Self-Care
For everyday back pain without red flags, most people get better with simple steps at home over a few weeks.
Move, do not freeze
Long bed rest used to be the advice. Research now shows that staying gently active helps you heal faster. Keep doing light daily activities, take short walks, and avoid only the movements that sharply increase your pain. A day or two of taking it easy is fine, but try not to stay in bed.
Use heat and cold
- Cold packs in the first day or two can calm swelling and dull sharp pain. Wrap ice in a cloth and apply it for about 15 to 20 minutes.
- Heat from a warm pad or shower after the first day helps loosen tight, achy muscles and a back spasm.
Manage the pain
Over-the-counter pain relievers such as ibuprofen, naproxen, or acetaminophen can take the edge off so you can keep moving. Follow the label and check with a pharmacist or doctor if you have stomach, kidney, liver, or heart concerns.
Rebuild your strength
- Gentle stretching for the lower back, hips, and hamstrings can ease tightness.
- Once the sharp pain settles, core-strengthening exercises help support the spine and reduce the chance of the pain coming back.
- A physical therapist can teach you a safe routine made for your body.
Fix the daily habits
Lift with your legs and keep loads close to your body. Set up your desk and chair so your screen is at eye level and your feet rest flat. Take breaks from sitting, and check that your mattress and pillow support good posture. Small changes like these often prevent the next round of upper or lower back pain.
How Back Pain Is Diagnosed
Most of the time, a doctor can figure out the cause of back pain from your history and a physical exam, without any imaging at all.
Your doctor will ask when the pain started, what makes it better or worse, whether it spreads to your legs, and whether you have any red-flag symptoms. During the exam, they may check how you bend and move, test the strength and feeling in your legs, and check your reflexes to see if a nerve is involved.
Imaging is not needed for most new back pain, and ordering it too early can lead to treatments you do not need. Scans become useful when red flags are present, when pain lasts beyond about four to six weeks, or when surgery is being considered. An X-ray can show bone problems like arthritis or a fracture. An MRI gives a detailed view of discs, nerves, and soft tissue and is the best tool for finding a herniated disc or pinched nerve. Blood tests may be ordered if an infection or inflammatory arthritis is suspected.
Getting the right diagnosis matters. The treatment for a muscle strain is very different from the treatment for a herniated disc, a fracture, or an inflammatory condition.
When to See a Doctor and Which Specialist
See a doctor if your back pain has not improved after a few weeks of self-care, keeps coming back, or is interfering with work, sleep, or daily life. You do not need to wait for it to become severe.
Your primary care doctor is usually the best first stop. They can examine you, rule out serious causes, prescribe stronger treatment if needed, and refer you if the pain does not settle.
Depending on what they find, you may be referred to one of these specialists.
- A physical therapist for hands-on treatment and a tailored exercise plan, often the most effective long-term fix for mechanical back pain.
- An orthopedic surgeon or spine specialist for structural problems such as a herniated disc, spinal narrowing, or a fracture, especially when nerve symptoms are present. Surgery is only considered for a small number of cases and usually only after other treatments have been tried.
- A rheumatologist if an inflammatory condition like ankylosing spondylitis or rheumatoid arthritis is suspected.
- A pain management doctor for chronic pain that needs a longer-term plan.
If you want to find an orthopedic or spine specialist close to home, you can search by state and city to see providers near you. Bringing a short note about when your pain started, what it feels like, and what you have already tried will help your visit go faster.

Frequently Asked Questions
Common questions about back pain
What causes a sore lower back?
The most common cause is a strained muscle or ligament from lifting, twisting, poor posture, or a sudden movement. Other causes include a herniated disc, arthritis, sciatica, and age-related wear on the spine. Most cases are not serious and improve within a few weeks.
How long does back pain usually last?
Most acute back pain gets better within two to six weeks with gentle activity and basic self-care. Pain that lasts longer than three months is called chronic and should be checked by a doctor. If your pain is getting worse instead of better, do not wait to be seen.
When should I worry about back pain?
Seek emergency care if you lose bladder or bowel control, have new leg weakness or numbness in the groin area, have a fever with the pain, or hurt your back in a fall or crash. Also see a doctor for pain with unexplained weight loss, a cancer history, or pain that will not ease at rest.
Should I rest or stay active with back pain?
Staying gently active helps you heal faster than long bed rest. Keep doing light daily activities and take short walks, avoiding only the movements that sharply increase your pain. A day or two of taking it easy is fine, but try not to stay in bed for long stretches.
What helps a back spasm at home?
Apply gentle heat to relax the tight muscle, take an over-the-counter pain reliever as directed, and avoid the movement that triggered it. Light stretching once the worst passes can help. If the spasm is severe, keeps returning, or comes with leg weakness, see a doctor.
Is back pain during pregnancy normal?
Yes, back pain is very common in pregnancy because the added weight and shifting posture load the lower back. Gentle stretching, good posture, supportive shoes, and heat usually help. Tell your doctor or midwife if the pain is severe, comes with cramping, or is paired with other symptoms.
Which doctor treats back pain?
Start with your primary care doctor, who can examine you and rule out serious causes. From there you may see a physical therapist for exercise-based care, an orthopedic or spine specialist for structural problems, or a rheumatologist if an inflammatory condition is suspected.
