What to Do for a Pulled Muscle in Your Lower Back

A pulled muscle in your lower back typically heals within two weeks with the right combination of rest, movement, and pain management. The key is to act quickly in the first 48 hours to control inflammation, then gradually return to normal activity rather than staying in bed. Here’s exactly what to do at each stage.

Ice First, Then Switch to Heat

For the first 48 hours after the injury, ice is your best tool. Wrap an ice pack in a thin cloth and apply it to the painful area for 15 to 20 minutes at a time, letting your skin warm up between sessions. The cold numbs pain and reduces swelling in the damaged muscle fibers.

After those first two days, switch to heat. A heating pad or hot water bottle wrapped in a towel, applied for 15 to 20 minutes at a time, increases blood flow to the injured area and helps the muscle relax and repair. Some people find alternating between ice and heat helpful during the transition period, but heat generally becomes the better option once the initial inflammation has settled.

Keep Moving (Carefully)

This is the part most people get wrong. Your instinct will be to lie flat and avoid all movement, but extended bed rest actually slows recovery. According to Harvard Health, too much time in bed weakens your muscles, can cause digestive problems, and even raises the risk of blood clots. If you need to rest, limit it to a few hours at a stretch and no more than a day or two total.

Clinical trials consistently show that an early return to normal activities, with rest breaks as needed, produces better outcomes than staying home for days on end. That doesn’t mean you should push through sharp pain or go back to heavy lifting. It means walking around the house, doing light daily tasks, and moving gently whenever you can tolerate it.

Pain Relief That Works

Over-the-counter anti-inflammatory medications like ibuprofen are the first-line recommendation from the American College of Physicians for this type of back pain. They reduce both pain and swelling. Muscle relaxants are another option if the spasms are severe.

You might wonder whether a topical pain gel would work just as well. A randomized trial published in the Annals of Emergency Medicine tested this directly in patients with acute low back pain. Oral ibuprofen outperformed topical anti-inflammatory gel, and combining the two offered no additional benefit over ibuprofen alone. If you’re choosing between a tube of gel and a pill, the pill is the better bet for back strains.

Gentle Stretches for the First Week

Once you can move without sharp, stabbing pain (usually after a day or two), gentle stretching helps restore flexibility and prevents the surrounding muscles from tightening up. All of these are done lying on your back, which keeps pressure off the spine.

  • Knee-to-chest stretch: Lie on your back with knees bent and feet flat on the floor. Pull one knee toward your chest with both hands, tighten your belly muscles, and press your spine into the floor. Hold for five seconds, then switch legs. Finish by pulling both knees up together.
  • Lower back rotation: From the same starting position, keep your shoulders flat on the floor and slowly roll both bent knees to one side. Hold for 5 to 10 seconds, then roll to the other side.
  • Pelvic tilts: Lying on your back with knees bent, tighten your belly muscles so your lower back lifts slightly off the floor. Hold five seconds. Then flatten your back by pulling your bellybutton toward the floor. Hold five seconds. Alternate between the two.
  • Bridge: From the same position, tighten your belly and glute muscles, then raise your hips until your body forms a straight line from knees to shoulders. Hold long enough for three deep breaths, then lower back down.
  • Cat stretch: On your hands and knees, slowly arch your back upward like a cat while dropping your head. Then let your belly sag toward the floor while lifting your head. Repeat 3 to 5 times, twice a day.

None of these should cause sharp pain. A mild pulling sensation is fine, but if any movement reproduces or worsens your pain, skip it and try again in a day or two.

How to Sleep With a Strained Back

Nighttime is often the worst part of a back strain because you can’t find a comfortable position. Small adjustments with pillows make a big difference.

If you sleep on your side, draw your knees up slightly toward your chest and place a pillow between your legs. This keeps your spine, pelvis, and hips aligned and takes pressure off the injured muscles. A full-length body pillow works well for this. If you sleep on your back, place a pillow under your knees to help your lower back maintain its natural curve. A small rolled towel tucked under your waist can add extra support. Stomach sleeping is the hardest position on a strained back, but if you can’t sleep any other way, slide a pillow under your hips and lower stomach to reduce the strain.

Realistic Recovery Timeline

Most people with a lower back strain see significant improvement within about two weeks. The first three to five days tend to be the worst, with pain gradually decreasing after that as the muscle fibers repair themselves. If your symptoms haven’t improved after two weeks, that’s a sign you may need further evaluation or treatment such as physical therapy.

Recovery doesn’t mean you’ll feel 100% at the two-week mark. Mild stiffness or soreness with certain movements can linger for a few more weeks, especially in the morning or after sitting for long periods. That’s normal and doesn’t mean you’ve reinjured yourself.

Preventing It From Happening Again

Back strains have a frustrating tendency to recur, especially if the core muscles that support your spine are weak. The same stretches listed above double as prevention exercises when done regularly. The bridge and cat stretch in particular strengthen the deep muscles around your spine and pelvis that act as a natural brace for your lower back.

Aim to do these exercises daily, even after the pain is gone. Building a consistent 15-minute routine is more effective than occasional intense workouts. Pay attention to how you lift heavy objects going forward: bend at the knees, keep the load close to your body, and avoid twisting while carrying weight.

Signs This Might Not Be a Simple Strain

Most pulled back muscles are painful but harmless. However, a few symptoms suggest something more serious is going on and require immediate medical attention:

  • Loss of bladder or bowel control: This can indicate cauda equina syndrome, a rare condition where nerves at the base of the spine are compressed. It’s a medical emergency.
  • Numbness in the groin or inner thighs: Another sign of nerve compression that needs urgent evaluation.
  • Progressive weakness in one or both legs: Especially if it’s getting worse rather than better over hours or days.
  • Severe pain with fever: Could indicate a spinal infection, which requires immediate treatment.

If your pain started without any obvious physical cause, is constant regardless of position, or wakes you from sleep, those patterns are worth getting checked out. A straightforward muscle strain almost always feels better in certain positions and worse in others. Pain that never changes with movement may have a different source.
