Written by Dr James Tan
Contents
Are you dealing with lower back pain? If yes, then you are not alone. Lower back pain is one of the most common health complaints worldwide, affecting individuals of all ages and lifestyles. Lower back pain can be acute (lasting a few days to weeks) or chronic (persisting for months or years). It is often linked to issues such as poor posture, muscle strain, degenerative conditions, or nerve-related disorders.
In this article, we discuss some of the most common causes of lower back pain that can help you determine what might be causing your back pain, symptoms to watch for and when to seek medical attention. We also discuss treatment options, lifestyle modifications, and some effective back pain exercises that can help manage the pain in addition to your doctor’s treatment.
What Causes Back Pain?
Some of the most common causes of lower back pain are discussed below:
Muscular & Skeletal Causes
Muscle Strains & Ligament Sprains
Muscle strain (pulled muscle) and ligament sprains occur due to sudden movements, excessive stretching, or improper posture. This is the most frequent cause of lower back pain, especially in individuals who lift heavy objects improperly or sit for long hours.
Symptoms:
Sudden or gradual lower back pain
Muscle stiffness and difficulty moving
Increased pain with movement, especially while bending or twisting
Treatment:
Rest, but avoid prolonged inactivity
Cold therapy for the first 48 hours to reduce swelling
Over-the-counter pain relief medications such as ibuprofen and paracetamol
Herniated or Bulging Discs
Our spinal discs act as cushions between vertebrae in the spinal column. A herniated or bulging disc occurs when the disc's soft inner material pushes through its outer layer, pressing on nerves. This can cause pain not only in the lower back but along one or both legs.
Symptoms:
Lower back pain that may radiate to the legs
Numbness, tingling, or weakness in one leg (sciatica)
Pain that worsens while sitting or bending forward
Treatment:
Physiotherapy to improve flexibility and core strength
Pain management with anti-inflammatory drugs
In severe cases, corticosteroid injections or surgery may be recommended
Degenerative Disc Disease (DDD)
As we age, our spinal discs naturally deteriorate, losing their cushioning ability. This can lead to chronic lower back pain and stiffness.
Symptoms:
Persistent lower back pain, that typically worsens by prolonged sitting
Pain that improves with movement or changing positions
Occasional pain flare-ups with increased stiffness
Osteoarthritis (OA) is the wear-and-tear of spinal joints, that leads to inflammation, stiffness, and pain. Spinal stenosis, often caused by OA, occurs when the spinal canal narrows and compresses nerves. This can result in pain and immobility.
Symptoms:
Pain that worsens with movement but eases with rest
Numbness or weakness in the legs
Difficulty standing or walking for long periods
Treatment:
Exercise therapy to strengthen back muscles
Medication for pain and inflammation
Surgical interventions in severe cases
Lifestyle & Postural Factors
Prolonged Sitting & Poor Ergonomics
Sitting for extended periods—especially with poor posture—places excessive pressure on the spine, leading to chronic discomfort. This can even cause spinal problems over time.
Symptoms:
Dull, aching pain lower back pain after prolonged sitting
Stiffness in the lower back, especially in the morning
Prevention:
Use lumbar support when sitting
Adjust workstation ergonomics in such a way that the screen at your eye level and knees should be bent at a 90-degree angle
Take breaks every 30–45 minutes to stretch and walk around a bit.
Heavy Lifting & Overexertion
Improper lifting techniques or sudden heavy exertion can strain back muscles and ligaments.
Symptoms:
Sharp pain immediately after lifting
Difficulty standing straight
Muscle spasms in the lower back
Prevention:
Adopt proper lifting techniques by lifting with your legs, not your back
Avoid twisting while lifting
Strengthen your core muscles for support
Obesity & Sedentary Lifestyle
Excess weight can put additional strain on spinal discs, accelerating degeneration and exacerbating spinal issues.
Symptoms:
Chronic lower back pain
Reduced mobility
Increased discomfort after standing or walking
Prevention:
Maintain a healthy weight through diet and exercise
Strengthen your core and back muscles
Stay active to promote spinal health
Medical & Neurological Causes
Sciatica (Nerve Compression)
Sciatica is a common cause of lower back pain, often accompanied by pain radiating to one or both legs. This condition occurs when the sciatic nerve (which runs from the lower back to the legs) is compressed, often due to a herniated disc or spinal stenosis.
Symptoms:
Sharp, shooting pain down the leg which may go up to the toes
Numbness or tingling sensation
Weakness in the affected leg
Treatment:
Stretching exercises (e.g., piriformis stretch)
Physiotherapy and anti-inflammatory medications
In severe cases, surgical decompression may be necessary.
Kidney Stones or Infections
Pain from kidney issues may be mistaken for back pain.
Symptoms:
Pain on one side of the lower back
Pain when urinating, fever, and nausea
Blood in the urine
Treatment:
Hydration and pain management
Medical treatment for kidney infections
Back Pain Symptoms to Watch For
Back pain can present with different intensities and for varying durations. Some cases of back pain are mild while some may point to more serious issues. Some mild symptoms of back pain can easily be managed at home. However, certain serious lower back pain symptoms must be assessed by a qualified specialist at the earliest.
Mild Symptoms (Can be Managed at Home)
Dull ache after prolonged sitting or standing
Stiffness in the morning
Pain that improves with movement
Serious Symptoms (Seek Medical Help)
Pain radiating down the legs (sciatica)
Weakness, numbness, or tingling in the legs
Loss of bladder or bowel control
Severe, persistent chronic back pain lasting more than 6 weeks
Effective Back Pain Treatments and Prevention Strategies
Lower back pain can often be managed with the right combination of home remedies, lifestyle changes, and medical interventions. Below is a detailed breakdown of effective treatment options:
Home Remedies for Back Pain Immediate Relief
Heat & Cold Therapy
Cold therapy (first 48 hours): Use cold compresses to reduce inflammation and numb pain during the initial presentation of back pain. Use an ice pack wrapped in a cloth for 15–20 minutes at a time.
Heat therapy (after 48 hours): use heat therapy to relax muscles and improve blood circulation. A heating pad or warm bath can also be helpful.
Gentle Stretching & Yoga
Incorporate lower back stretches like the cat-cow stretch, child’s pose, and seated forward bend to improve flexibility.
Yoga can help strengthen the core and promote better spinal alignment.
Over-the-Counter (OTC) Pain Relief for Lower Back Pain
NSAIDs (e.g., ibuprofen, naproxen): Reduce inflammation and pain.
Paracetamol: Helps with mild discomfort, though it doesn't address inflammation.
Proper Sleeping Positions
Sleep on your side with a pillow between your knees to keep the spine neutral.
If you sleep on your back, place a pillow under your knees to reduce lumbar pressure.
Massage Therapy & Acupressure
Regular massage therapy can relieve muscle tension and improve circulation.
Acupressure mats and trigger point massage tools can help release tight areas.
Lifestyle Adjustments for Long-Term Back Health
Improve Posture & Ergonomics
When sitting: Keep your feet flat on the ground, back supported, and knees at 90 degrees. Use lumbar support if needed.
When standing: Avoid slouching, distribute weight evenly, and engage your core.
At work: Use a standing desk or take frequent breaks to move around.
Regular Exercise & Core Strengthening
Engaging in low-impact exercises (walking, swimming, Pilates) strengthens core muscles, reducing strain on the lower back.
Strength training for the back and abs improves spinal stability.
Maintain a Healthy Weight
Excess weight increases spinal strain and can worsen disc degeneration.
A balanced diet and regular exercise can prevent obesity-related back pain.
Lift Properly to Avoid Injury
Always bend at the knees, not the waist, and keep heavy objects close to your body.
Avoid twisting while lifting.
Stay Hydrated & Eat a Nutrient-Rich Diet
Hydration: Keeps spinal discs lubricated.
Calcium & Vitamin D: Essential for bone health to prevent osteoporosis.
Medical Interventions for Persistent or Severe Back Pain
Physiotherapy & Rehabilitation
A physical therapist can design a personalised exercise plan to improve mobility and reduce pain.
Spinal manipulation (chiropractic adjustments) may provide relief.
Medications for Chronic Pain Management
Muscle relaxants (for severe muscle spasms).
Nerve pain medications (e.g., gabapentin for sciatica-related pain).
Corticosteroid injections for inflammation in severe cases.
Surgical Treatment for Lower Back Pain (For Severe Cases)
Surgery for lower back pain is considered only if conservative treatments fail. Options include:
Discectomy (removal of a herniated disc).
Spinal fusion (joining two vertebrae for stability).
Laminectomy (removing bone spurs that compress nerves).
Alternative Treatments
Acupuncture: Can relieve chronic back pain by stimulating nerve function.
While consulting an orthopaedic specialist for back pain and following the recommended treatment plan is crucial, there are some exercises for back pain that can aid in recovery.
Knee-To-Chest Stretch
This exercise for back pain helps relax the muscles in the lower back and is also effective in relieving sciatic pain.
Lie flat on your back with your knees bent and feet flat on the floor.
Gently bring one knee towards your chest and press it against the chest, using your hands, for 10 seconds.
Release the leg and bring it back to the starting position.
Repeat for the other leg.
You can even bring both knees to the chest and hold the position for 10 seconds.
Do 2-3 reps of this exercise twice a day.
Lower Back Rotational Stretch
Another effective back pain exercise is the lower back rotational stretch.
Lie flat on your back with your knees bent and feet flat on the ground.
Roll both your bent knees towards one side; the knees don’t necessarily have to touch the ground. Hold this position for a few seconds.
Return back to the starting position.
Repeat the same by rolling the knees to the other side.
Do 2-3 reps of this exercise in the morning and at night.
Glute Bridge Stretch
The glute bridge stretch is one of the effective back stretches for back pain that helps strengthen the glute muscles and improves flexibility and range of motion of the lower back.
Start with lying flat on your back, knees bent, and feet flat on the ground. Arms and hands should be on your side on the ground.
With your shoulders and feet fixed to the ground, tighten your abdomen and glute muscles and raise your stomach/abdomen area above the ground. Feel the stretch in your back. However, only raise your back to the point where you feel a light stretch.
Hold the position for a few seconds and gently return back to the starting position.
Start with five reps at a time and increase them as your stamina and flexibility improve.
Cobra Stretch
The cobra stretch is one of the stretches for lower back pain that helps relieve pain and is very relaxing.
Lie on your stomach with your shoulders off the ground and your hands flat on the ground under the shoulders.
Press down on the ground with your hands, straightening the elbows, lifting, and extending your upper body upwards. Feel the stretch in your abdomen and lower back. Hold the position for a few seconds.
Gently return back to the starting position while exhaling.
Do at least five reps.
Cat Stretch
Another of the lower back pain exercises that can be effective in providing back pain relief is the cat stretch.
Get on your all fours with your hands and bent knees on the ground.
Inhale and arch your back up to bring it up towards the ceiling.
Hold the position for 3-5 seconds.
Slowly exhale and bring your back down, arching it towards the ground this time.
Repeat for 3-5 reps.
Pelvic Tilt
The last lower back pain stretch is the pelvic tilt. This stretch strengthens the abdominal muscles and helps relieve back pain.
Lie flat on the ground with your knees bent and feet firmly on the ground. Arms and hands should be lying flat on your sides.
Tighten your abdominal muscles and press your lower back towards the ground, flattening it to touch the ground. Hold the position for 3-5 seconds.
Gently relax your abdomen and bring your back to the natural position,
Repeat 3 to 5 reps.
These are some of the exercises and stretches that can help relieve back pain.

Frequently Asked Questions
Is lower back pain always serious?
Not necessarily. Most lower back pain is due to muscle strain, poor posture, or mild disc issues and improves with home care. However, if your pain is persistent, severe, or accompanied by numbness, weakness, or bowel/bladder issues, seek medical attention.
How do I know if my back pain is muscular or nerve-related?
The symptoms of muscular back pain and nerve-related back pain are different. Muscular pain feels like soreness, stiffness, or dull aching. It is localised pain that worsens with movement and improves with rest, heat therapy, and massage. However, nerve-related back pain e.g. sciatica presents as sharp, shooting, or burning pain that may radiate down the legs. Pain may be accompanied by numbness, tingling, or weakness in the legs or feet. Moreover, the pain does not improve with rest and may worsen with prolonged sitting.
What are the best sleeping positions for lower back pain?
The best sleeping position for lower back pain is to sleep on your side with a pillow between the knees or on your back with a pillow under the knees. Avoid sleeping on your stomach as it causes misalignment and stress on the spine.
How can I relieve lower back pain at home?
Try the following home remedies for lower back pain:
Apply cold packs (first 48 hours) followed by heat therapy.
Perform gentle stretching exercises like knee-to-chest stretches.
Take anti-inflammatory medication (if necessary).
Maintain good posture and avoid prolonged sitting.
Use a lumbar support cushion if you sit for long periods.
Can stress or anxiety cause lower back pain?
Yes. Stress and anxiety can lead to increased muscle tension, especially in the back and shoulders.
How long does lower back pain last?
Acute pain: 2–6 weeks (caused by minor injuries or strains).
Chronic pain: Over 3 months (needs medical intervention).
