Quick Answer

A back strain is an injury to a muscle or tendon, while a back sprain is an injury to a ligament, caused by repetitive motion, overuse or trauma. [1] Symptoms include pain that worsens with movement, spasms and reduced range of motion. [1] Rest, ice, compression and NSAIDs help in the first 48 hours, and most people recover fully within two weeks. [1]

Key takeaways

  • A strain injures a muscle or tendon; a sprain injures (stretches or tears) a ligament. [1] [7]

  • The lumbar lower back is the usual site because it bears much of your body weight during walking, running, and lifting. [1]

  • Typical symptoms: pain that worsens with movement, cramping/spasms, reduced range of motion, and sometimes a pop or tear at the moment of injury. [1]

  • Risk factors: excessive lower back curve, obesity, weak back or abdominal muscles, tight hamstrings, and push-pull sports. [1]

  • The first 48 hours matter most: rest, ice 20 minutes at a time, compression, and NSAIDs. [1]

  • After 24 to 48 hours, resume normal activity; extended bed rest or immobility delays recovery. [1] [2]

  • Most people fully recover in about two weeks [1]; see a provider if symptoms persist or red flags appear.

What the research says

  • Resuming activity is supported by trial evidence. A Cochrane review of ten randomized trials found moderate-quality evidence that people with acute low back pain may gain small benefits in pain relief and function from advice to stay active compared with advice to rest in bed. In two trials (401 participants), the standardized mean differences were 0.22 for pain (95% CI 0.02 to 0.41) and 0.29 for function (95% CI 0.09 to 0.49). (Dahm et al., Cochrane Database Syst Rev, 2010) [2]

  • Heat has more trial support than cold for low back pain, though the evidence base is limited. A Cochrane review of nine trials (1,117 participants) found that, in two trials of 258 people with acute and subacute low back pain, heat wrap therapy reduced pain after five days compared with oral placebo. The authors found insufficient evidence to judge cold therapy and conflicting evidence on differences between heat and cold, and called for higher-quality trials. (French et al., Cochrane Database Syst Rev, 2006) [3]

  • Excess weight raises the risk of low back pain. In a meta-analysis of 33 studies, obesity was linked to higher odds of low back pain in the past 12 months (pooled OR 1.33; 95% CI 1.14 to 1.54), of seeking care for low back pain (OR 1.56; 95% CI 1.46 to 1.67), and of chronic low back pain (OR 1.43; 95% CI 1.28 to 1.60). In cohort studies, obesity was associated with a higher incidence of low back pain (OR 1.53; 95% CI 1.22 to 1.92). (Shiri et al., Am J Epidemiol, 2010) [4]

What Are Back Strains and Sprains?

A strain injures a muscle or tendon; a sprain injures a ligament. The lumbar spine takes most of the load.

Back strains and sprains are common injuries that can occur following repetitive motions, overuse, or trauma. A strain is an injury to a muscle or tendon. A sprain is an injury to a ligament. [1] [7] Pulling, twisting, or tearing of these tissues in your back can cause sprains or strains. [1]

Your back, especially the lumbar section of your lower back, bears much of your body's weight during walking, running, lifting, and other activities. [1] There are many potential causes for back pain, and strains and sprains are common causes of temporary pain. [1]

Strain vs. Sprain: What's the Difference?

Feature

Back strain

Back sprain

Tissue injured

Muscle or tendon

Ligament

How it happens

Twisting or pulling the muscle/tendon; a single improper lift; prolonged repetitive movement

A fall, sudden twist, or blow that forces a joint out of its normal position

Mechanism

Overstressed muscle fibers or tendon tear

Ligament stretched beyond its normal range of movement

Chronic form

Yes: chronic strain results from prolonged, repetitive overuse

Less commonly described as chronic

What Are the Symptoms of a Strained or Sprained Back?

Common symptoms of a back strain or sprain, from movement-related pain to a pop at the time of injury.

Back strain or sprain symptoms may include:

Symptom

What it looks or feels like

Pain that gets worse when you move

Discomfort that intensifies with activity

Muscle cramping or spasms

Sudden, uncontrollable muscle contractions

Decreased function or range of motion

Difficulty walking, bending forward or sideways, or standing straight

A pop or tear at the time of injury

A sudden sensation felt in some cases at the moment the injury occurs

What Causes Muscle Strains or Sprains in Your Back?

Twisting or pulling a muscle or tendon can result in a strain. It can also happen after a single instance of improper lifting or another activity that overstresses your back muscles. A chronic (long-term) strain usually results from overuse after prolonged, repetitive movement of your muscles and tendons. [1]

A sprain often occurs after a fall or sudden twist, or a blow to your body that forces a joint out of its normal position. All of these conditions stretch one or more ligaments beyond their normal range of movement, causing injury. [1]

What are the risk factors for back strains and sprains?

Several factors can put you at greater risk for sprains or muscle strain in your back:

Risk factor

Why it matters

Curving your lower back excessively

Puts extra stress on lumbar tissues

Having obesity

Excess weight is a common risk factor for lower back (lumbar) strain and injuries

Having weak back or abdominal muscles

Less support for the spine during activity

Having tight hamstrings

Tight thigh muscles alter how the back carries load

Playing push-pull sports

Sports like weightlifting and football stress the back repeatedly

How Are Back Strains and Sprains Diagnosed?

Healthcare providers can usually diagnose back strains and sprains based on a physical examination and your medical history, including a review of your symptoms and how the injury occurred. [1]

If you have severe symptoms like weakness or loss of function, your provider might take a spine X-ray or MRI. This imaging can help rule out a fractured (broken) or herniated (bulging) disk. [1]

Diagnostic step

Purpose

Physical examination

Assesses the injured area and movement limits

Medical history review

Covers symptoms and how the injury happened

Spine X-ray

Rules out a fractured (broken) spine

MRI

Rules out a herniated (bulging) disk and shows soft-tissue detail

How Are Back Strains and Sprains Treated?

Back sprain and back strain treatments are essentially the same and often take place in two phases. [1]

Phase one: the first 48 hours

The first phase happens over the first 48 hours after your injury. The goal is to reduce pain, spasm, and swelling. [1] Phase one usually involves rest, ice packs, compression therapy, and NSAIDs. [1]

The two-phase plan: rest, ice, compression, and NSAIDs first, then a return to normal activity.

Phase one step

How to do it

Rest

The less you use your injured muscles, tendons, or ligaments, the quicker you'll recover; resting gives your body adequate time to heal

Ice packs

Place an ice pack wrapped in a towel on the affected area for 20 minutes at a time, several times a day

Compression therapy (pressure)

Wrapping the injured area applies pressure that reduces swelling and pain; most important during the first 24 to 48 hours

NSAIDs (nonsteroidal anti-inflammatory drugs)

Over-the-counter medications like ibuprofen (Advil® or Motrin®) or naproxen sodium (Aleve®, Anaprox®, Naprelan®, or Naprosyn®) help reduce pain and swelling

Phase two: after 24 to 48 hours

After the first 24 to 48 hours, you should try to resume normal routines and activities. Extended bed rest or immobility (nonmovement) will prolong your symptoms and delay recovery. [1] [2] Most people with sprains or strained back muscles improve in about two weeks. [1] If symptoms persist, you might need additional treatment.

How Long Does a Back Strain Last?

Most people with a back strain make a full recovery within two weeks of starting treatment. [1] If your symptoms last longer, let a healthcare provider know.

What's the most common complication?

The most common complication of a back strain or sprain is being less active. That can lead to weight gain, loss of bone density, and loss of muscle strength and flexibility in other areas of your body [1], which is one reason resuming movement after the first 48 hours matters.

When Should I See My Healthcare Provider?

Call a healthcare provider if you have any of the following:

Warning sign

Detail

Severe back pain

Pain so bad you can't walk more than a few steps

Numbness

In the injured area or down your leg

History of lower back problems

A history of lower back pain or lumbar spine injuries

Unusual lump or shape

A lump or area with an unusual shape

Sleep-disrupting pain

Pain that interferes with your sleep

Obvious weakness

In an extremity (hands or feet) after an injury

Intense or frequent back pain may mean you have a back injury that's more severe than a sprain or strain. [1] Reach out to a healthcare provider.

Can I Prevent Muscle Strains in My Back?

It's not possible to prevent all back injuries, but you can take steps to lower your risk:

Prevention step

How it helps

Eat a healthy, well-balanced diet

Keeps your bones and muscles strong

Maintain a healthy weight

Excess weight is a common risk factor for lower back strain

Exercise regularly, including stretching

Keeps your joints flexible and your muscles in good condition

Practice fall-prevention safety

Wear properly fitting shoes; keep stairs and walkways free of clutter

Use good body mechanics

Keep your back straight and shoulders back; when sitting, keep knees bent and feet flat on the floor; don't over-reach, avoid twisting; when lifting, bend your knees and use your strong leg muscles

Stop using tobacco

Nicotine interferes with blood flow to your muscles; this includes smokeless tobacco and vaping

Conclusion

Back strains and sprains are among the most common causes of temporary back pain, and they come down to a simple distinction: a strain injures a muscle or tendon, while a sprain injures a ligament. [1] The lumbar lower back takes the brunt of these injuries because it carries much of your body weight through every walk, run, and lift. [1] A single improper lift, a sudden twist, a fall, or years of repetitive strain can all be the trigger, and risk climbs with obesity, weak core muscles, tight hamstrings, and an excessive lower back curve. [1]

The recovery playbook is straightforward. The first 48 hours are about controlling pain, spasm, and swelling with rest, towel-wrapped ice packs for 20 minutes at a time, compression, and over-the-counter NSAIDs. [1] Then, and this is the part people often get wrong, movement is the medicine: resuming normal routines after that initial window matters, because extended bed rest prolongs symptoms. [1] Most people make a full recovery within two weeks. [1] If your pain prevents you from walking more than a few steps, causes numbness down your leg, disrupts your sleep, or lingers beyond two weeks, it's time to talk to a healthcare provider.

[1]

Can back strains and sprains be prevented?

You can't prevent all back injuries, but you can lower your risk by eating a healthy, balanced diet, maintaining a healthy weight, exercising regularly with stretching, practicing fall prevention, using good body mechanics when sitting, standing, and lifting, and stopping tobacco use, since nicotine interferes with blood flow to your muscles. [1]

Why does the lower back get injured so often?

Your back, especially the lumbar section of your lower back, bears much of your body's weight during walking, running, lifting, and other activities [1], making it a common site for strain and sprain injuries.

Can lifting a box the wrong way cause a strain?

Yes. A strain can happen after a single instance of improper lifting or another activity that overstresses your back muscles. [1] When lifting, bend your knees and use your strong leg muscles to help balance the load [1], keeping your back straight and shoulders back. [1]
