Most pulled back muscles heal on their own within one to two weeks with the right combination of rest, movement, and pain management. The key is balancing enough rest to calm the initial spasm with enough gentle activity to prevent stiffness and muscle weakening. Here’s what to do from the moment it happens through full recovery.
The First 48 Hours: Reduce Pain and Spasm
Your immediate priority is calming the inflammation and muscle spasm. For the first 24 to 48 hours, apply ice to the injured area for no more than 20 minutes at a time, then wait at least 20 minutes before applying it again. Wrap the ice pack in a thin cloth to protect your skin. You can repeat this cycle several times throughout the day.
Over-the-counter anti-inflammatory medication helps reduce both pain and swelling during this window. Ibuprofen is a common choice: a starting dose of 400 mg, followed by 200 to 400 mg every four hours as needed, up to four doses in 24 hours. Naproxen is another option, starting at 440 mg with follow-up doses of 220 mg every 8 to 12 hours. If you’re over 65, keep naproxen to no more than 220 mg every 12 hours. Don’t use either medication for longer than 10 days without checking with your doctor.
Rest during this phase, but don’t overdo it. Lying down for a few hours at a stretch is fine. Staying in bed for days is not.
Why Too Much Bed Rest Makes Things Worse
It feels logical to stay flat until the pain fades, but extended bed rest actually delays recovery. Your muscles lose conditioning and tone quickly when they’re not being used. Prolonged immobility can also cause constipation and, in rare cases, blood clots in the veins of your pelvis and legs.
Clinical trials consistently show that returning to normal activities early, with rest breaks as needed, leads to faster recovery than staying home from work for days on end. After the first 24 to 48 hours, start moving around as your pain allows. Walk short distances. Stand and shift your weight. The goal isn’t to push through sharp pain, but to avoid letting your body stiffen up completely.
When to Switch From Ice to Heat
Ice is best in the first day or two when inflammation peaks. After that initial window, heat often feels more effective because it loosens tight muscles and increases blood flow to the injured area, which supports healing. A warm towel, heating pad, or warm bath all work. Follow the same 20/20 rule: 20 minutes on, 20 minutes off. Some people find alternating ice and heat helpful during the transition period. Go with whatever gives you more relief.
Gentle Stretches That Help
Once the worst of the spasm has calmed (typically after 48 to 72 hours), gentle stretching can relieve tension and restore range of motion. Two safe options to start with:
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 while tightening your abdominal muscles and pressing your spine into the floor. Hold for five seconds, then switch sides. Repeat two to three times per side.
Lower back rotational stretch: Lie on your back with knees bent and feet flat. Keeping your shoulders firmly on the floor, slowly roll both bent knees to one side. Hold for 5 to 10 seconds, return to center, then repeat on the other side. Do two to three repetitions each way.
Both of these stretches should feel like a gentle pull, not sharp pain. If a stretch makes your symptoms worse, stop. And if you’re dealing with a severe strain or recurring injuries, working with a physical therapist to build a safe exercise plan is worth it.
Sleeping With a Pulled Back Muscle
Nighttime can be the hardest part of a back strain because you lose conscious control over your posture. A few pillow adjustments make 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 aligns your spine, pelvis, and hips so your back muscles aren’t working to hold you in position. A full-length body pillow works well here.
If you sleep on your back, place a pillow under your knees to maintain the natural curve of your lower back and help relax the surrounding muscles. A small rolled towel under your waist can add extra support.
Stomach sleeping puts the most strain on a pulled back muscle. If you can’t sleep any other way, slide a pillow under your hips and lower stomach to reduce the arch in your lower spine.
Recovery Timeline
Mild strains often feel noticeably better within a few days and resolve within one to two weeks. Moderate strains with more significant muscle fiber damage can take three to six weeks. During this time, you should see steady improvement, even if it’s gradual. Pain that stays the same or worsens after a week of self-care is worth getting evaluated.
As you recover, focus on rebuilding core strength and flexibility. Weak abdominal and back muscles are the most common reason people re-injure the same area. Even 15 minutes a day of basic core exercises, once you’re past the acute phase, helps prevent the next episode.
Signs Something More Serious Is Happening
A pulled muscle, while painful, is a straightforward injury. Certain symptoms suggest the problem goes beyond a muscle strain. Call for emergency care if you lose the ability to move a leg. Seek immediate medical attention if you notice new or worsening numbness, tingling, or weakness in your legs, arms, or buttocks, or if you lose bladder or bowel control. These can signal nerve compression or spinal cord involvement that requires a different level of treatment.
