If you’ve just pulled your lower back, the best thing you can do is stay calm and keep moving gently. Most lower back strains heal on their own within a few days to a few weeks, and the steps you take in the first 48 hours can make a real difference in how quickly you recover. Here’s exactly what to do, from the moment it happens through your return to normal activity.
What to Do in the First 48 Hours
Your instinct might be to lie down and stay there, but prolonged bed rest actually slows recovery. Harvard Health Publishing notes that well-designed clinical trials consistently show an early return to normal activities, with some rest as needed, works better than staying home for an extended period. If you need to lie down, limit it to a few hours at a stretch and no longer than a day or two total.
Instead, focus on gentle movement. Walk around your home, shift positions frequently, and avoid sitting or standing in one spot for long periods. The goal is to keep blood flowing to the injured muscles without aggravating the strain. Avoid heavy lifting, twisting, and any movement that causes sharp or shooting pain.
Ice and Heat
Apply ice wrapped in a towel for 10 to 15 minutes to reduce swelling and numb the area. A few hours later, switch to heat for 15 to 20 minutes to relax tight muscles and increase blood flow. You can alternate between the two throughout the day. Some people find ice more helpful in the first 24 hours when inflammation peaks, then prefer heat after that, but either is fine at any point if it feels good.
Over-the-Counter Pain Relief
Acetaminophen (Tylenol) is typically the first choice because it has fewer side effects than anti-inflammatory options. Stay under 3,000 mg in a 24-hour period, and avoid it entirely if you have liver disease. Anti-inflammatory pain relievers like ibuprofen can help reduce both pain and swelling, but they carry risks of stomach irritation and kidney strain with prolonged use. If you’re still relying on over-the-counter pain relievers after two weeks, that’s a sign to check in with a healthcare provider.
How to Sleep With a Pulled Back
Nighttime is often the hardest part of a back strain because you can’t control your position while asleep. A few adjustments 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 aligns your spine, pelvis, and hips and takes pressure off the lower back. A full-length body pillow works well if you tend to shift around.
If you sleep on your back, place a pillow under your knees. This relaxes the lower back muscles and preserves the natural curve of your spine. A small rolled towel tucked under your waist can add extra support. Stomach sleeping puts the most strain on a pulled back, so try to avoid it during recovery if possible.
Gentle Movements That Help
Starting gentle stretches early, even within the first day or two, helps your muscles recover faster than staying still. One of the safest starting moves is the knee-to-chest stretch: lie on your back with your knees bent and feet flat on the floor, then use both hands to pull one knee toward your chest. Tighten your abdominal muscles and press your lower back into the floor. Hold for five seconds, return to the starting position, and repeat with the other leg.
Pelvic tilts are another good option. Lying in the same position, gently flatten your lower back against the floor by tightening your stomach muscles, hold briefly, and release. These movements activate the deep core muscles that stabilize your spine without putting load on the injured area. Do a few repetitions several times a day rather than one long session. If any movement causes sharp pain, stop and try again the next day.
Sitting and Working With a Strain
If you need to work at a desk, how you sit matters more than how long you sit, though shorter bouts are still better. Place a rolled-up towel or small cushion at the curve of your lower back for support. Keep your hips and knees at a right angle, and adjust your chair height so you can sit close to your work surface. Rest your elbows and arms on the chair or desk with your shoulders relaxed rather than hunched forward.
Get up and walk around every 30 minutes, even if it’s just for a minute. Sitting in one position for hours tightens the muscles around the injury and increases stiffness. If your chair reclines, leaning back slightly (around 100 to 110 degrees) reduces the load on your lower spine compared to sitting perfectly upright.
When You Can Return to Exercise
Most mild back strains allow a return to light activity within a few days and normal exercise within two to four weeks. Rather than following a fixed timeline, pay attention to functional milestones. You’re ready to increase activity when your symptoms are decreasing during daily tasks like sitting and walking, morning stiffness is improving, and you can move through your normal range of motion without a sharp pain response.
Before returning to sports or heavy lifting, you should be able to perform sport-specific movements at your usual power with no increase in pain during or after the activity. Confidence matters too. If you’re guarding or flinching during a movement, your body is telling you it’s not ready. Rushing back before meeting these benchmarks is one of the most common reasons people re-injure their lower back.
Warning Signs That Need Immediate Attention
The vast majority of pulled backs are simple muscle strains that heal without complications. But certain symptoms suggest something more serious is going on. Get medical help promptly if you experience any of the following:
- Numbness or tingling in your groin, inner thighs, or buttocks (sometimes called saddle area numbness)
- Loss of bowel or bladder control, including new difficulty urinating or incontinence
- Weakness in one or both legs, especially if it’s getting worse
- Severe pain that doesn’t improve with rest, position changes, or medication and keeps escalating over days
- New difficulty walking or a foot that drags or feels floppy
These can indicate nerve compression or other conditions that need treatment beyond home care. Pain that gradually improves, even if slowly, is reassuring. Pain that steadily worsens over several days is not.
What Recovery Actually Looks Like
The first two to three days are usually the worst. You’ll feel stiff in the morning, sore after sitting, and limited in how far you can bend or twist. By the end of the first week, most people notice meaningful improvement in their pain levels and range of motion. By two to three weeks, the majority of simple strains are mostly resolved, though you may still feel twinges with certain movements.
Full recovery, meaning you can do everything you did before without thinking about your back, typically takes three to six weeks for a moderate strain. During this time, gradually increasing your activity level is the single most effective thing you can do. Every day you can do a little more than the day before is a sign you’re on track.
