How Long Does a Pulled Back Muscle Take to Heal?

The short answer

Most pulled back muscles improve clearly within 2–6 weeks. A mild strain may settle in 1–2 weeks; a severe tear or a repeatedly injured muscle can take 2–3 months. NHS guidance for sprains and strains is that most improve within 2 weeks, while severe cases can take up to 8 weeks. That does not mean lying still for weeks; it means avoiding triggers and reloading gradually.

Judge recovery by three abilities, not just “does it still hurt”: can you turn without pain, can you sit down and stand up, and can you walk briskly without being worse 24 hours later? If pain has not trended down after 2 weeks, or you have leg numbness, weakness, bladder or bowel changes, or severe pain after trauma, this is not a simple strain.

Mild, moderate, or severe?

A muscle strain is overstretching or tearing of muscle fibers or the tendon. Clinicians often grade it:

• Mild (grade I): a few fibers are injured. Local soreness, tenderness, and pain with certain movements, but strength is mostly normal. Most improve in 1–2 weeks.
• Moderate (grade II): more fibers are torn. Pain is clearer, with possible swelling or bruising, and everyday movements are limited. Recovery often takes several weeks.
• Severe (grade III): a complete tear. Severe pain, marked swelling and bruising, obvious weakness, and sometimes a palpable gap. This needs medical assessment; recovery is often measured in months.

The back muscles are deep, so most people cannot grade their own injury accurately. A more practical check:

• Can you walk and move around the house?
• Is the pain trending down day by day?
• Do you have leg numbness, weakness, or bladder or bowel changes?
• Was there a fall, or do you have osteoporosis?

No leg symptoms, no systemic symptoms, and a gradual improvement with rest and gentle movement point more toward a mild-to-moderate strain. If any of those is not true, get assessed.

What healing looks like

Inflammation is part of the repair

For the first 48–72 hours, the area becomes inflamed: blood flow increases, tissue swells, and pain sensitivity rises. This is the beginning of repair, not a process to eliminate completely. Complete immobility, icing until numb, or long-term high-dose painkillers can slow recovery. The goal is to control excessive pain and swelling while keeping gentle movement.

Repair and remodeling need measured load

After a few days, the body lays down new collagen, but the fibers are initially disorganized and weak. Without any tension, scar tissue can become short and stiff; with too much load too soon, it can tear again. The key is gradual loading without a clear flare: walking and daily activity first, then light strength work, then return to sport.

Why the same injury keeps returning

After a strain, local strength, endurance, and proprioception decline. If you wait only for pain to disappear and then return to the previous training load, the same movement can re-injure the area. Adding 2–4 weeks of progressive strength work before returning to full activity is more reliable than “no pain, go back to normal.”

It is not the same as a disc herniation

A strain usually hurts in the lower back muscles or sacrum, has a spot you can press, and follows twisting, bending, or a sudden effort. Disc-related pain more often travels down the leg with numbness or weakness and worsens with coughing. The two can coexist and can be confused; leg nerve symptoms need medical assessment.

A traditional Chinese medicine view

Traditional theory often describes an acute strain as “qi stagnation, blood stasis, and injury to the sinews,” but this is not the same as a blocked blood vessel. It looks at the mechanism, swelling, bruising, whether the pain is sharp or distending, and whether heat helps. The acute phase is about settling pain and moving stagnation; the recovery phase is about restoring nourishment and load tolerance.

Three common patterns:

• Qi stagnation and blood stasis: sudden sharp pain after a twist or lift, a fixed spot, worse with pressure, possible bruising, limited turning.
• Cold-damp retention: tightness and heaviness after cold exposure, better with heat, worse in damp weather.
• Sinew malnourishment: recurrent old injuries, aching weakness, slow recovery, fatigue.

These map one way to constitution tendencies: blood-stasis toward fixed pain and recurrent injuries; Yang-deficiency toward cold-triggered tightness; phlegm-dampness toward heaviness and slow recovery. Constitution tendencies are for daily care only and cannot replace assessment for a tear, fracture, or nerve injury.

The evidence boundary: NCCIH notes that acupuncture has a relatively stronger evidence base for some pain conditions, while acupressure and herbal medicine have more mixed evidence. A systematic review of acupressure for low back pain suggested possible relief, but the studies were heterogeneous. Do not use aggressive massage or scraping to “break up the bruise” in the acute phase; it can increase bleeding and swelling.

The first 72 hours and beyond

First 48–72 hours

• Relative rest: avoid heavy lifting, twisting, prolonged sitting, and the movement that caused the injury. Short walks are fine; you do not need complete bed rest.
• Cold or heat: for a fresh injury with local heat and swelling, a short cold pack for 10–15 minutes over cloth can be used; do not ice until numb. After 48–72 hours, or once swelling settles, switch to heat for 15–20 minutes.
• Compression and position: the back is hard to elevate, so avoid prolonged standing or sitting. If there is marked swelling, a soft brace can provide light compression, but it should not restrict breathing.
• Pain relief: acetaminophen or an NSAID can be used short-term as directed. Ask a doctor or pharmacist first if you have stomach or kidney disease, are pregnant, or take blood thinners.
• No forced stretching: stretching into sharp pain can re-injure the tissue. Keep movement gentle and within a comfortable range.

Day 3 to week 2

• Return to daily activity: short walks, alternating sitting and standing, light household tasks; change position every 45 minutes.
• Pain-free movement: pelvic tilts, one knee to chest, and cat-cow, 8–10 times each.
• Heat and light massage: massage the surrounding muscles, not the tender spot directly. Stop if pain increases.
• Check the 24-hour response: if you are not clearly worse the next day, the dose is reasonable. If you are, go back a step.

Weeks 2–6

• Add strength: glute bridges, bird dog, side plank, and wall sits, 2–3 times a week, starting with 2 sets.
• Add endurance: walking for 15–30 minutes, increasing gradually.
• Test before returning to sport: can you turn, bend, walk briskly, and stand on one leg without pain? Are you no worse 24 hours after exercise?
• Do not jump back to full load: use 50%–70% of your previous training for 1–2 weeks, then progress.

Traditional self-care

Keep the acute phase gentle; add nourishment and load gradually.

Acupressure

In the acute phase, press distal points gently rather than the injured area. About 60 seconds per point, aiming for a mild ache.

BL40 (Weizhong) Location: center of the crease behind the knee. Traditional use: classically used for lower back tightness and referred strain pain. Avoid with varicose veins, a history of blood clots, or local swelling.

BL57 (Chengshan) Location: on the back of the calf, at the top of the “V” formed when you rise onto your toes. Traditional use: used for calf tightness and back-leg referral. Press gently.

LI4 (Hegu) Location: on the back of the hand, between the first and second metacarpal bones, about halfway along the second metacarpal. Traditional use: a general pain and qi-moving point. Do not use during pregnancy.

Food

Eastern-style options:

• Notoginseng and yam porridge (recovery phase): 100 g yam and 50 g rice simmered in 800 ml water for 30 minutes; mix 1–2 g notoginseng powder into a little warm water and add after turning off the heat. Traditionally used for stasis. Do not use during pregnancy, with blood thinners, or with bleeding disorders; consult a practitioner before using it as medicine.
• Ginger and jujube tea: 3 slices fresh ginger and 3 pitted jujubes simmered in 400 ml water for 10 minutes. Warming; suits cold-triggered tightness.
• Black bean and walnut porridge: 30 g soaked black beans, 15 g walnuts, and 40 g rice simmered for 40 minutes. Traditionally warming and supportive in the recovery phase.

Western-style options:

• Egg and whole-grain toast: 2 slices whole-grain bread, 1 egg, tomato, and lettuce. A quick source of protein.
• Banana yogurt bowl: 150 g plain yogurt, half a banana, and 20 g oats. A practical post-exercise snack.
• Lentil vegetable soup: 50 g red lentils, carrot, celery, and tomato simmered for 25 minutes. A lighter recovery dinner.

Mind and emotions

Recovery is not a straight line. Feeling better one day and sore the next is normal. Do not test the tender spot repeatedly. Set a weekly goal such as “walk 15 minutes without pain” rather than “be back to normal by the end of the month.” If anxiety is high, ask a clinician or physical therapist for a graded plan instead of adding load on your own.

Movement

Cat-cow 8–10 times, glute bridges 10–15 times for 2 sets, bird dog 8 times per side, wall sits 20–30 seconds for 2–3 sets, and walking from 10 minutes upward. Keep the range comfortable.

Routine

Prioritize sleep; repair happens overnight. Stand up every 45 minutes. Keep the lower back warm after the acute phase. Avoid heavy drinking during recovery; it affects sleep and protein synthesis.

A 6-week recovery timeline

Phase	Goal	What you can do	Avoid
Days 1–3	Settle pain and protect	Short walks, light activity, cold/heat	Heavy lifting, twisting, strong stretching
Days 4–7	Return to activity	10–15 minute walks, pain-free movement	Prolonged sitting, aggressive massage
Week 2	Return to routine	15–20 minute walks, light chores	Sudden speed or impact
Weeks 3–4	Add strength	Glute bridges, bird dog, side plank, 2–3 times a week	Heavy loads, explosive movements
Week 5	Add endurance	25–30 minute walks, light loading	Returning to full training at once
Week 6	Return to sport	50%–70% of previous load, check 24-hour response	Ignoring pain signals

Before increasing load, ask: was I clearly worse 24 hours after the last session? If yes, go back a step. If no, add about 10%.

Returning to exercise

• Mild strain: daily activities pain-free in 1–2 weeks; low-intensity exercise can resume in 2–4 weeks.
• Moderate strain: clear improvement in 2–6 weeks; returning to the previous sport often takes 6–8 weeks.
• Severe tear: needs medical assessment; recovery is measured in months and should not be self-graded.
• Recurrent injury: time is not the only criterion; strength and endurance matter more.

Three gates for return: pain-free daily movement, strength close to the other side, and no worsening 24 hours after exercise. If any gate is not met, keep training rather than rushing back.

When to see a doctor

• Severe pain after trauma, inability to bear weight, marked swelling or bruising, or a palpable gap—assess for a tear or fracture;
• Leg numbness, weakness, foot drop, or bladder or bowel changes—seek emergency care;
• Fever, chills, or increasing redness, heat, and swelling—rule out infection;
• Osteoporosis, long-term steroid use, or a fall in an older adult—rule out a compression fracture;
• No downward trend after 2 weeks, or week-by-week worsening;
• Persistent night pain, weight loss, or cancer history.

Common questions

Heat or ice for a pulled back muscle?

For a fresh injury with local heat and swelling, a short cold pack for 10–15 minutes is reasonable. After 48–72 hours, or once swelling settles, switch to heat for 15–20 minutes. Use a cloth barrier and avoid extreme temperatures. People with diabetes or reduced skin sensation need to protect against cold or heat injury.

Can I go back to training once the pain is gone?

Not immediately at full load. Pain relief means inflammation has settled, not that strength and endurance are back. Use 50%–70% of your previous load for 1–2 weeks and check the 24-hour response. Re-injury often happens in the “pain is gone, back to normal” stage.
