Most pulled back muscles heal on their own within two to four weeks with the right combination of rest, movement, and pain management. The key is finding the balance between protecting the injured muscle and staying active enough to prevent stiffness and deconditioning. Here’s how to handle each phase of recovery.
What Happens When You Pull a Back Muscle
A pulled muscle (strain) means the muscle fibers in your back have been stretched or torn. This usually happens during a sudden twist, heavy lift, or awkward movement, though it can also result from prolonged poor posture. The severity breaks into three grades:
- Grade I (mild): Overstretched fibers with minor tearing. Heals in about 2 to 4 weeks.
- Grade II (moderate): A partial tear of the muscle. Expect around 2 months for full recovery.
- Grade III (severe): A complete tear that may require surgery, with recovery taking 6 to 9 months or longer.
Most pulled back muscles fall into Grade I or II territory. The pain is usually localized to one area, gets worse with movement, and may come with muscle spasms or stiffness. If you can still walk and function (even if it hurts), you’re likely dealing with a mild to moderate strain that you can manage at home.
The First 48 Hours: Ice and Relative Rest
Right after the injury, your goal is to reduce inflammation and give the muscle a chance to begin healing. Apply a cold pack wrapped in a thin towel for no more than 20 minutes at a time, four to eight times a day, for the first two days. Cold narrows blood vessels and limits swelling in the damaged tissue.
Rest during this window, but don’t take to your bed for days. Extended bed rest actually slows recovery from a back strain. Clinical trials consistently show that an early return to normal activities, with rest breaks as needed, produces better outcomes than staying home in bed. Too much time lying down weakens muscles, can cause constipation, increases the risk of blood clots, and often worsens mood. Limit bed rest to short periods when the pain is at its worst, and aim to keep moving gently throughout the day.
Switching to Heat After Day Two
Once the initial acute phase passes, usually within a couple of days, you can switch from ice to heat. A heating pad, warm towel, or warm bath helps relax tight muscles and increases blood flow to the injured area, which supports healing. Use heat for 15 to 20 minutes at a time, and always place a layer between the heat source and your skin to avoid burns. Some people find alternating heat and cold helpful during this transition period.
Managing Pain With Over-the-Counter Medication
Anti-inflammatory painkillers like ibuprofen (200 to 400 mg every 6 to 8 hours, up to 1,200 mg per day) or naproxen (250 mg every 6 to 8 hours, or 500 mg every 12 hours, up to 1,000 mg per day) reduce both pain and swelling. Take them with food to protect your stomach. These are most useful in the first week or two. Acetaminophen is an alternative if you can’t take anti-inflammatories, though it won’t address inflammation directly.
Sleeping Without Making It Worse
Nighttime is often the hardest part of a back strain because you can’t easily control your position. A few pillow adjustments make a real 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 area. A full-length body pillow works well here. If you sleep on your back, put a pillow under your knees to help your lower back muscles relax and maintain their natural curve. A small rolled towel under your waist can add extra support. Stomach sleeping puts the most strain on your back, so try to avoid it during recovery.
Gentle Exercises to Start Healing
Movement is medicine for a pulled back muscle, but the right kind matters. Start these exercises once the sharpest pain begins to ease, typically a few days after the injury. Move slowly, breathe normally, and stop if any exercise causes a significant increase in pain.
Single Knee to Chest
Lie on your back with both knees bent. Tighten your core by drawing your belly button toward your spine, then grasp the back of one thigh and pull that knee gently toward your chest. Hold for 30 seconds, then switch legs. Do this twice daily. This stretch releases tension in the lower back without forcing it into a vulnerable position.
Lumbar Rotation
Lie on your back with knees bent, feet flat, and arms at your sides. Tighten your core and let both knees roll gently to one side. Hold for 5 seconds, return to center, and repeat on the other side. Do 10 repetitions per side. This restores rotational mobility in the lower spine.
Hamstring Stretch
Tight hamstrings pull on your pelvis and increase strain on the lower back. Lie on your back with both knees bent. Raise one leg so the knee is directly over your hip, interlock your fingers behind that thigh, and slowly straighten the knee until you feel a stretch in the back of your thigh. Hold for 5 seconds, then lower. Repeat 10 times on each side.
Seated Forward Bend
Sit in a chair with your feet flat on the floor. Slowly bend forward at the hips, reaching toward the floor. Let your head hang and breathe normally. Hold for 5 seconds, then sit back up. Repeat 10 times. This gently stretches the entire posterior chain of muscles along your back.
Hip Flexor Stretch
Lie on your back at the edge of a bed and let the leg closest to the edge hang down off the side. You’ll feel a stretch in the front of your hip and into your lower back. Hold for 10 to 30 seconds. Repeat twice daily on each side. Tight hip flexors are a common contributor to back muscle strain, so this stretch addresses one of the root causes.
Returning to Normal Activity
For a mild strain, you can usually resume most daily activities within a week or two, gradually increasing intensity. The muscle isn’t fully healed yet, but controlled loading actually strengthens the repair. Avoid heavy lifting, sudden twisting, and high-impact exercise until you can move through a full range of motion without pain. Walking is one of the best activities during recovery because it keeps the back muscles active without overloading them.
A moderate strain takes longer. You may feel functional within a few weeks, but full recovery and a return to demanding physical activity typically takes closer to two months. Pushing too hard too soon is the most common reason back strains recur. If the pain plateaus or returns after a period of improvement, scale back your activity level for a few days before trying again.
Signs That Need Medical Attention
A standard pulled muscle doesn’t cause nerve symptoms. Seek immediate medical care if you experience numbness, tingling, or weakness in your legs, feet, or groin area. Loss of bladder or bowel control is a medical emergency that can signal compression of the nerves at the base of the spine. Also get evaluated right away if you’re unable to move a leg at all, or if back pain comes with severe abdominal pain, as these can indicate problems beyond a muscle strain.
If your pain hasn’t improved at all after two to three weeks of home treatment, or if it’s getting steadily worse rather than better, that’s worth a visit to your doctor. What feels like a pulled muscle can occasionally turn out to be a disc problem, a joint issue, or something else that benefits from a different treatment approach.
