Most pulled back muscles heal within about two weeks with the right combination of rest, ice, gentle movement, and over-the-counter pain relief. The key is managing pain in the first few days while avoiding the common mistake of staying in bed too long, which actually slows recovery. Here’s what to do from the moment it happens through full healing.
What Happens When You Pull a Back Muscle
A pulled muscle (strain) means some of the fibers in the muscle have been stretched beyond their limit or torn. Strains are graded by severity. A mild strain involves microscopic tears with no real loss of strength. A moderate strain means a larger number of fibers are damaged, and you’ll notice weakness along with pain. A severe strain is a complete tear of the muscle, with a total loss of function in that area.
The vast majority of pulled back muscles fall into the mild or moderate category. You’ll feel a sudden sharp pain, often during lifting, twisting, or bending. The area may stiffen up quickly, and you might notice swelling or muscle spasms within the first few hours. Complete tears are rare in the back and typically involve a traumatic injury.
First 72 Hours: Ice and the 20/20 Rule
Ice is the best tool for the first three days. It reduces swelling and numbs the area enough to take the edge off. Follow the 20/20 rule: apply ice for no more than 20 minutes, then give yourself a 20-minute break before reapplying. Wrap ice or a cold pack in a thin towel to protect your skin.
After 72 hours, you can switch to heat. A heating pad or warm towel helps relax tight muscles and improve blood flow to the injured tissue, which supports healing. The same 20/20 timing applies: 20 minutes on, 20 minutes off.
Pain Relief That Works
Over-the-counter anti-inflammatory medications are effective for short-term pain management. Ibuprofen can be taken at 200 to 400 mg every six to eight hours, up to 1,200 mg per day. Naproxen works at 250 mg every six to eight hours or 500 mg every 12 hours, up to 1,000 mg per day. Both reduce inflammation and pain simultaneously, which makes them more useful than acetaminophen alone for muscle injuries.
Keep these medications to the short term. If you’re still relying on them after a week or two, that’s a sign the injury may need professional evaluation.
Move Early, but Move Gently
One of the biggest mistakes people make with a pulled back muscle is staying in bed for days. Research consistently shows that early movement leads to faster recovery. One study found that starting rehabilitation two days after a soft-tissue injury instead of nine days later helped athletes return to activity 20 days sooner. The goal isn’t to push through pain. It’s to avoid prolonged stillness, which weakens the surrounding muscles and stiffens the joints.
Within the first day or two, start with short, slow walks around your home. Keep them to five or ten minutes. If walking increases your pain significantly, scale back, but don’t stop moving entirely. Light activity keeps blood flowing to the injured area and prevents the muscles around the strain from tightening up in compensation.
Stretches That Help Recovery
Once the sharp initial pain begins to ease (usually after two to three days), gentle stretches can speed healing and prevent stiffness from setting in. Physical therapists at the Hospital for Special Surgery recommend several that target the lower back without putting excessive load on the injured area.
Single knee to chest: Lie on your back with both knees bent. Tighten your abs by pulling your belly button toward your spine. Grasp the back of one thigh and bring that knee toward your chest. Hold for 30 seconds, then switch legs. Do this twice daily.
Lumbar rotation: Lie on your back with knees bent, feet flat, arms at your sides. Tighten your abs and gently let both knees roll to one side. Hold for five seconds, return to center, and repeat on the other side. Do 10 repetitions per side.
Hamstring stretch: 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 five seconds, then repeat 10 times on each side. Tight hamstrings pull on the pelvis and increase strain on the lower back, so this stretch matters more than it might seem.
Press up on elbows: Lie on your stomach with elbows bent at your sides, palms flat. Let your lower back arch naturally as you press up onto your forearms. Hold 10 seconds, then lower back down. Repeat up to 10 times daily.
With all of these, stop if any stretch produces sharp or worsening pain. Mild discomfort and a pulling sensation are normal. Anything beyond that means you’re pushing too far.
How to Sleep With a Pulled Back Muscle
Nighttime is often the hardest part. The wrong sleeping position can leave you stiff and in more pain by morning. Pillow placement makes a significant 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 your lower back. A full-length body pillow works well here.
If you sleep on your back, place a pillow under your knees. This relaxes the back muscles and preserves the natural curve of your lower spine. A small rolled towel under your waist can add extra support if you still feel strain.
Stomach sleeping is the toughest position for a back injury, but if you can’t sleep any other way, place a pillow under your hips and lower stomach to reduce the arch in your lower back.
Typical Recovery Timeline
Most people with a mild to moderate pulled back muscle recover fully within about two weeks. The first three to five days tend to be the worst, with significant stiffness and pain. After that, symptoms gradually improve as the torn fibers repair themselves. You should notice meaningful progress week over week. If your pain hasn’t improved at all after two weeks, or if it’s getting worse rather than better, additional treatment such as physical therapy or imaging may be needed.
Preventing It From Happening Again
A pulled back muscle is more likely to happen a second time if the core muscles that support your spine remain weak. Three exercises, recommended by the Mayo Clinic, build that stability when done consistently.
Pelvic tilts: Lie on your back with knees bent and feet flat. Tighten your belly muscles so your lower back lifts slightly away from the floor. Hold five seconds. Then flatten your back, pressing your belly button toward the floor. Hold five seconds. Start with five repetitions a day and work up to 30 over time.
Bridges: From the same starting position, tighten your abs and glutes, then raise your hips until your body forms a straight line from knees to shoulders. Hold long enough to take three deep breaths, then lower back down. Start with five reps and build to 30.
Cat stretch: On your hands and knees, slowly arch your back upward like a cat, pulling your belly toward the ceiling while dropping your head. Then let your back and belly sag toward the floor as you bring your head up. Repeat three to five times, twice a day.
These take about 15 minutes and, done regularly, strengthen the muscles that act as a brace for your spine during lifting, bending, and twisting.
Signs Something More Serious Is Wrong
Most pulled back muscles are painful but harmless. However, a few symptoms signal something beyond a simple strain. Seek emergency medical care if your back pain causes new bowel or bladder control problems, as this can indicate nerve compression that requires urgent treatment. Pain that radiates down one or both legs below the knee, progressive weakness in your legs, or pain accompanied by unexplained fever or weight loss also warrant immediate evaluation. These symptoms don’t point to a muscle strain. They suggest nerve involvement or an underlying condition that needs a different approach entirely.
