The lower (lumbar) spine allows your body to turn, twist, and bend. It also gives strength for standing, walking, and lifting. The lower back is involved in almost all movement. Pain in the lower back is very common.
Low back pain is usually caused by lifting, exercising, falling, or being in a car crash
The most common cause of low back pain is muscle strain
Strengthening your stomach, hip, and back muscles can help prevent low back pain
You can treat low back pain by avoiding activities that stress your back, taking pain relievers, and using cold or heat on your back, but low back pain usually heals on its own
Older people with low back pain without an obvious cause or with the "warning signs" below may need to be seen by a doctor
When should I see a doctor?
See your doctor right away if you have low back pain and any of these warning signs:
Weakness in one or both legs
Problems with urinating or passing stool (poop)
Light-headedness or fainting
Severe pain anywhere in your belly
See your doctor within a day if you have low back pain and any of these warning signs:
History of cancer
Severe pain at night
You’re age 55 or older and there’s no obvious reason, such as an injury causing your pain
You’re at increased risk of infection because of medicines you take, recent surgery or injury, drug use or because you have HIV or AIDS
If your pain isn't severe and you have no warning signs, you can wait several days to see a doctor.
What causes low back pain?
Doctors may not always be able to tell what's causing your low back pain. The most common cause of low back pain is:
Muscle strain or ligament sprains (ligaments are short, tough bands of tissue that hold your bones together at a joint)
This may happen on one or both sides of your back. Your pain gets worse with movement and better with rest.
Other common causes include:
Nerve compression (when something pushes on a nerve), which can happen with conditions like osteoarthritis Osteoarthritis (OA) Arthritis is a group of diseases that makes your joints hurt, swell up, and turn red.

A disk is the spongy tissue between back bones (vertebrae) that lets your spine bend. When a disk is torn or squeezed, jelly-like material can bulge out (herniate) and can put pressure on a nerve. Coughing or sneezing may make nerve compression pain worse.

Your pain may be worse if you:
Lift something heavy the wrong way
Are very tired
Have poor posture (you don’t stand up straight)
Don’t have good muscle strength in your back, stomach, and hip muscles (core muscles)
What is sciatica?
Sciatica Sciatica Sciatica is pain along the sciatic nerves. These nerves run from the lower back, through the buttocks, and down the legs, ending just below the knee. A herniated disk, complications of osteoarthritis... read more is pain caused by pressure on the sciatic nerve. The sciatic nerve is the largest nerve in the back. It runs from your lower spine down the back of your leg. Any cause of low back pain may result in sciatica.
Usually sciatica affects only one side. You may feel pins-and-needles, tingling, or numbness in part of your leg. You may have achy or shooting pain down the back of your leg to your knee or to your foot. Continued pressure on the nerve is serious and may lead to long-term weakness and numbness in your leg.
What will happen at my doctor visit?
Your doctor will ask questions about your symptoms and health history and do a physical exam.
In certain cases, your doctor may do tests such as x-rays Plain X-Rays A plain x-ray is an imaging test that takes a picture of the inside of your body. It uses a low dose of x-ray radiation. X-rays show body parts according to how dense (solid) they are.

You don't always need x-rays or an MRI when you have back pain.
How will my doctor treat low back pain?
Doctors base treatment on the cause of your back pain and how long it has lasted. But in general, most low back pain goes away with good home care.
If your pain is severe, you may need to rest in bed for a day or two
Too much bed rest is bad because it weakens your back muscles, which can make your pain worse
Light activity actually helps—ask your doctor what you should and shouldn't do
Apply heat or cold to the painful area—cold is best during the first 2 days after an injury, then use heat
Take pain medicine such as acetaminophen, ibuprofen, or naproxen
When lying down, you may be more comfortable on your side with your knees bent
As soon as possible, your doctor will have you start doing mild exercises to strengthen your back. Stronger muscles keep your back stable so it will hurt less. You may be sent for physical therapy Physical Therapy (PT) Physical therapy, a component of rehabilitation, involves exercising and manipulating the body with an emphasis on the back, upper arms, and legs.

They can also teach you how to lift and move properly so you can work safely.

There are many different types of arthritis. Osteoarthritis is the most common type of arthritis. In osteoarthritis... read more , you may try:
Treatment by a chiropractor
For long-lasting pain, doctors may suggest:
Transcutaneous electrical nerve stimulation (TENS), an at-home electrical therapy that gives you a gentle tingling feeling and can be used several times per day—your doctor will send you to a physical therapist to help you learn how to use this device
Injecting a corticosteroid (such as dexamethasone or methylprednisolone) plus a numbing medicine into the epidural space (the space between the spine and the outer layer of tissue covering your spinal cord)
There are many different types of back surgery. Typically, doctors recommend surgery only when you have signs of severe nerve compression or if your pain is very bad and isn't helped by all the other treatments.
How can I prevent low back pain?
Do exercises to stretch and strengthen your stomach, hip, and back muscles
Keep your back straight when standing and sitting (slouching stresses your back)
Sit with your feet on the floor, not with your legs crossed
Don't stand or sit for long periods
When lifting items, lift with your legs, not your back
Exercises to Prevent Low Back Pain
Lie on the back with the knees bent, the heels on the floor, and the weight on the heels. Press the small of the back against the floor, contract the buttocks (raising them about half an inch from the floor), and contract the abdominal muscles. Hold this position for a count of 10. Repeat 20 times.
Lie on the back with the knees bent and feet on the floor. Place the hands across the chest. Contract the abdominal muscles, slowly raising the shoulders about 10 inches from the floor while keeping the head back (the chin should not touch the chest). Then release the abdominal muscles, slowly lowering the shoulders. Do 3 sets of 10.
Lie flat on the back. Place both hands behind one knee and bring it to the chest. Hold for a count of 10. Slowly lower that leg and repeat with the other leg. Do this exercise 10 times.
Sitting Leg Stretch
Sit on the floor with the knees straight but slightly flexed (not locked) and the legs as far apart as possible. Place both hands on the same knee. Slowly slide both hands toward the ankle. Stop if pain is felt, and go no farther than a position that can be held comfortably for 10 seconds. Slowly return to a sitting position. Repeat with the other leg. Do this exercise 10 times for each leg.
