What Is Low Back Pain?
Low back pain can feel like a stabbing, burning, or aching pain. It can be constant or come and go during the course of the day.
While most low back pain resolves over time, episodes of low back pain often return. You can treat and prevent low back pain with lifestyle changes and care from your doctor.
What causes lower back pain?
Low back pain can have many causes, such as:
- A herniated disc.
- A sprain or strain from overuse, repeated movements, or a single, awkward movement.
- A tumor (this is a rare).
- An infection (this is rare).
- Ankylosing spondylitis.
- Arthritis.
- Lumbar spinal stenosis.
- Osteoporosis.
- Scoliosis, or a curve of the spine.
Your low back pain could also be from something not listed above.
What are low back pain risk factors and complications?
Low back pain is more likely in people over age 30. Chronic low back pain is especially common between the ages of 50 and 60, according to the National Library of Medicine.
Besides age, your lifestyle can contribute to low back pain.
Lower back pain risk factors
Certain risk factors can make lower back pain more likely, including:
- A lack of exercise, as weak muscles in the abdomen and back can increase the risk of low back strain.
- A misalignment in the bones of your spine, or vertebrae, due to an injury or genetics.
- Age, especially if you're over 30.
- Being overweight.
- Engaging in frequent repetitive movements that put pressure on the lower back, like lifting, pushing, pulling, or twisting movements.
- Having poor posture.
- Sitting in a poorly designed chair for a long time, or driving for long periods without taking a break.
- Smoking, which can increase the risk of health issues that cause low back pain, like herniated discs and osteoporosis.
- Stress, including stress due to depression, anxiety, or poor sleep.
Complications of lower back pain
Left untreated, back pain can worsen over time.
People with low back pain may exercise less, increasing their risk of many diseases, including diabetes and heart problems.
Low back pain can also make it hard to engage with friends or family. It can impact your sleep and how well you're able to do your job, and make leisure activities less enjoyable.
Long-term or recurring back pain is a serious health problem that requires expert care.
How can I prevent my risk of lower back pain?
You can help prevent low back pain if you:
- Avoid lifting things that are too heavy. Ask someone to help you.
- Avoid sitting or standing in one position for too long.
- Eat a balanced diet to maintain a healthy weight.
- Sit up straight, with both feet on the floor.
- Strengthen the muscles in your abdomen, glutes, hips, and lower back. You can search online for exercises to prevent lower back pain or work with a physical therapist.
- Use an ergonomic chair when sitting for long periods.
- Use proper lifting technique — bend at the knees and engage the legs when lifting.
How common is low back pain?
Lower back pain is very common, with 75% to 85% of Americans getting it at some point in their lives, according to the American Association of Neurological Surgeons.
For some people, low back pain is chronic, meaning it lasts longer than 12 weeks or frequently returns. About 8% of Americans suffer from chronic low back pain, according to the National Center for Complimentary and Integrative Health.

What Are the Signs and Symptoms of Low Back Pain?
Depending on the cause, people with low back pain may experience one or more of the following symptoms:
- A burning pain.
- A dull ache.
- A sudden, sharp pain.
- Difficulty standing up straight.
- Stiffness in the low back.
When should I see a doctor about my low back pain symptoms?
See your doctor if your low back pain does not go away after a few weeks, or comes with other concerning symptoms.
You should always see a doctor if you have:
- Low back pain after a fall or other injury, which could suggest a fracture.
- Lower back pain that occurs with a fever or weight loss. This could be a sign of a more serious health problem.
- Lower back pain that shoots down the leg.
- Problems with bladder or bowel control. This may mean something is compressing the nerves in the spine and requires medical attention to avoid nerve damage.
- Severe back pain, such as pain that interferes with sleep or makes focusing at work or school challenging.
- Weakness, numbness, or tingling in one or both legs, which could be due to nerve compression.

How Do You Diagnose Lower Back Pain?
Many providers can diagnose low back pain. You might see your primary care doctor, a physical therapist specializing in spine, a sports medicine doctor, or a surgeon.
To diagnose lower back pain, your doctor will ask when the pain started. They will want to know how the pain feels — sharp, burning, or aching — and what makes it better or worse. They will also ask about your daily activities to see if your lifestyle may contribute to your back pain.
Your doctor may ask you to walk or do specific exercises. They may have you lie on a table while they move your legs to see how this affects your pain. They may also examine your lower back and legs to check for signs of swelling or weakness.
Most cases of low back pain do not need imaging tests. Doctors can often diagnose the cause based on your symptoms, lifestyle factors, and the physical exam.
Tests to diagnose low back pain
For back pain that does not go away, is very severe, or comes with other concerning symptoms, your doctor may order tests.
They will choose which test to run based on whether the problem seems related to the bones or soft tissues.
Options include:
- Bone density study — To help diagnose osteoporosis.
- Bone scan — Uses a radioactive tracer to look for breaks, infections, or tumors that don't show up on an x-ray.
- CT scan.
- Electromyography and nerve conduction velocity tests — Measure how electrical signals travel from the nerves in your back to other parts of your body.
- MRI.
- X-ray.

How Do You Treat Low Back Pain?
Treatment for low back pain depends on what is causing it. In many cases, low back pain requires more than one type of therapy.
Doctors usually start with lifestyle changes and medication, only considering surgery if those do not work. The goal of treatment is to dramatically reduce back pain and, ideally, resolve it completely.
Lifestyle changes for low back pain
Your doctor will discuss your lifestyle and suggest changes you can make to reduce your back pain.
These may include:
- Adjusting how you lift heavy objects.
- Changing your sitting and standing posture.
- Losing weight.
- Stretching and exercising regularly.
- Using an ergonomic chair and sleeping on a firm mattress.
Medicines for low back pain
Your doctor may suggest over-the-counter (OTC) or prescription medicines. Nonsteroidal anti-inflammatory drugs (NSAIDs) are helpful for lower back pain but may not be appropriate for everyone.
Physical therapy for low back pain
A primary spine practitioner is a physical therapist specializing in the spine. They will teach you exercises to strengthen specific muscles in your back, abdomen, glutes, and legs. Over time, this will improve the support for your spine and prevent pain.
Rest for low back pain
Your doctor may advise you to only sit or stand for a certain amount of time each day. They may also tell you to avoid specific movements, like lifting, and avoid sports until your pain resolves.
Steroid injections for low back pain
For pain that shoots from the lower back down the leg, known as sciatica, steroid injections can help. Studies show steroid injections at the base of the spine can improve pain for about a month or so. These injections can help in combination with lifestyle changes, which may take longer to work.
Surgery for low back pain
Sometimes, lower back pain requires surgery. Doctors only recommend surgery when other treatments do not work, or if needed to avoid nerve damage.
Various surgical techniques can help to stabilize the spine and prevent pain.
For example, the surgeon may replace worn or damaged discs that do not stay in place or properly cushion the vertebrae. They may fuse parts of the vertebrae together to make the spine more stable. They can also remove bone spurs that can grow in the spine and compress nerves.
While surgery can relieve pain for some, it carries risks, including infection and nerve damage. It also has a long recovery time, taking about six weeks before people can return to light activity. This is why doctors only suggest surgery when it is likely to be successful and is necessary.
Other remedies
Some people find relief in remedies like massage, acupuncture, or heat (from a hot bath or heating pad). Psychological services can help when stress adds to low back pain or depression makes lifestyle changes difficult.
