Most pulled back muscles heal within two to six weeks with the right combination of rest, movement, and self-care. The key is managing pain and inflammation in the first few days, then gradually reintroducing activity so the muscle rebuilds stronger than before. Here’s how to move through each phase of recovery.
What a Pulled Back Muscle Feels Like
A pulled (strained) back muscle causes pain that stays localized to the injured area. You’ll typically feel a sore, aching, or tight sensation that gets worse when you move, twist, or bend. Muscle spasms and stiffness are common, especially in the first few days. The pain may spike with certain positions but generally doesn’t travel down your legs or into your arms.
This is an important distinction. If your pain radiates into your leg as a sharp or shooting sensation, or you notice numbness, tingling, or weakness in your limbs, the problem is more likely a herniated disc pressing on a nerve rather than a simple muscle pull. Pain that worsens when you sit, cough, or sneeze also points toward a disc issue. And if you experience any loss of bladder or bowel control alongside severe back pain, that requires immediate medical attention.
The First 48 Hours: Ice, Rest, and Pain Relief
Right after the injury, your priority is reducing inflammation and giving the torn muscle fibers a chance to begin healing. Apply a cold pack wrapped in a thin towel to the sore area for no more than 20 minutes at a time, four to eight times per day, for the first two days. Cold constricts blood vessels, which limits swelling and numbs the area.
For pain relief, over-the-counter anti-inflammatory medications like ibuprofen or naproxen tend to work better than acetaminophen for back pain because they reduce both pain and inflammation. Acetaminophen is gentler on the stomach and still helps with pain, but it doesn’t address the inflammatory component. If your stomach is sensitive, acetaminophen is a reasonable starting point.
Rest during this phase, but don’t overdo it. Limit time lying down to a few hours at a stretch, and no more than a day or two total. Prolonged bed rest actually slows recovery by weakening the muscles that support your spine. Light movement, even just walking around the house, keeps blood flowing to the injury and prevents stiffness from setting in.
Days 3 Through 7: Switch to Heat and Start Moving
Once the initial acute phase passes (usually around day two or three), you can transition from ice to heat. A heating pad, warm towel, or warm bath relaxes tight muscles, improves blood flow to the injured tissue, and eases stiffness. Use heat for 15 to 20 minutes at a time, and always place a layer between the heat source and your skin.
This is also when gentle movement becomes your best medicine. Short walks, even five or ten minutes at a time, are a good starting point. Avoid lifting, twisting, or any motion that reproduces sharp pain. The goal is to stay active within a pain-free range rather than pushing through discomfort.
Gentle Stretches for Early Recovery
Once the sharpest pain has subsided, usually within the first week, you can begin simple stretches to restore flexibility. Two stretches recommended by the Mayo Clinic are especially useful for pulled back muscles:
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 abdominal muscles, and press your spine into the floor. Hold for five seconds, return to start, and repeat with the other leg.
Pelvic tilt: 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 relax. Next, flatten your back by pulling your bellybutton toward the floor. Hold five seconds, relax, and repeat. Start with five repetitions a day and slowly work up to 30 over the coming weeks.
Both of these stretches are low-impact and put minimal stress on the injured area. If either movement causes sharp or worsening pain, back off and try again in a few days.
Sleeping Without Making It Worse
Nighttime can be the hardest part of a back strain because you’re stuck in one position for hours. Strategic pillow placement makes a significant difference.
- Side sleepers: Draw your legs up slightly toward your chest and place a pillow between your knees. This keeps your spine, pelvis, and hips aligned and takes pressure off the injured muscle. A full-length body pillow works well here.
- Back sleepers: Place a pillow under your knees to help your lower back relax into its natural curve. A small rolled towel under your waist can provide additional support.
- Stomach sleepers: This position is hardest on a strained back, but if you can’t sleep any other way, place a pillow under your hips and lower stomach to reduce the arch in your spine.
Nutrition That Supports Muscle Repair
Your body needs raw materials to rebuild damaged muscle fibers, and what you eat during recovery genuinely matters. Protein is the most critical nutrient. During an injury, aim for about 1.5 to 2 grams of protein per kilogram of body weight per day. For a 180-pound person, that works out to roughly 30 grams at each meal and 15 to 20 grams in snacks. If you’re doing any rehab exercises or physical therapy, having 15 to 30 grams of protein afterward helps your muscles recover from the session.
Beyond protein, several micronutrients play direct roles in tissue repair. Vitamin C helps your body produce collagen, the structural protein that repairs tendons, ligaments, and muscle tissue. Zinc supports cell growth and wound healing. Omega-3 fatty acids (found in fatty fish, walnuts, and flaxseed) may enhance muscle repair and prevent muscle loss during periods when you’re less active. If you spend most of your time indoors or live in a northern climate, check whether your vitamin D levels are adequate, since low levels can slow healing.
Weeks 2 Through 6: Building Back Strength
As pain continues to decrease, your focus should shift from stretching to strengthening. The muscles that run along your spine and the deep abdominal muscles that wrap around your torso act as a natural brace for your back. When these are weak, the muscles that got injured in the first place are left doing more work than they should, which is often how the strain happened.
Start with bodyweight exercises like bridges, bird-dogs, and modified planks. Keep repetitions low and increase gradually. A physical therapist can design a program tailored to your specific injury, which is especially valuable if you’ve strained your back before or if the pain is taking longer than expected to resolve.
Walking remains one of the best activities throughout recovery. It’s low-impact, strengthens the muscles that support your spine, and improves circulation to the healing tissue. Swimming and water walking are also excellent options because the buoyancy takes weight off your back while still allowing you to build strength.
Preventing the Next Strain
A back strain is more likely to happen again once it’s happened once, so long-term prevention is worth the effort. The core exercises you started during recovery should become a permanent habit. Even 15 minutes a day of back-focused stretching and strengthening reduces your risk significantly. Consistency matters more than intensity.
Pay attention to how you lift heavy objects. Bend at the knees, keep the load close to your body, and avoid twisting while carrying weight. If you sit for long stretches during work, get up and move for a few minutes every hour. Prolonged sitting places more load on your lower back than standing does, and the muscles gradually fatigue and become more vulnerable to strain.
When Recovery Is Taking Too Long
Most mild to moderate back strains improve noticeably within two to three weeks, with full recovery by six weeks. If your pain is severe, hasn’t improved after a few weeks, or is accompanied by leg weakness, numbness, or tingling, the injury may be more than a simple muscle pull. Imaging and a professional evaluation can rule out disc problems or other structural issues that require a different treatment approach.
