Why Sitting Can Make Lower Back Pain Worse and What You Can Do About It

Have you ever spent a few hours sitting at your desk, only to stand up and feel an ache or stiffness in your lower back? Maybe your back starts bothering you during a long drive, or you notice discomfort after relaxing on the couch.

Lower back pain from sitting is a common concern, particularly for people who work at a desk, drive frequently, or spend extended periods in one position. While sitting itself isn't necessarily harmful, staying in the same position for too long can make existing back pain worse.

At Shift Physiotherapy & Wellness in Edmonton, our physiotherapists help people understand what may be contributing to their lower back pain and find practical ways to manage symptoms.

TL;DR: What You Should Know About Lower Back Pain From Sitting

• Prolonged sitting can aggravate lower back pain, especially when you remain in the same position for extended periods.

• Possible contributing factors include muscle stiffness, sensitivity to certain movements, spinal disc conditions, and reduced activity.

• There isn't one perfect sitting posture. Changing positions regularly is often more helpful than trying to sit perfectly straight all day.

• Movement and exercise can help. Regular breaks, walking, and building strength may reduce discomfort.

• Physiotherapy can help identify contributing factors and develop a treatment plan suited to your daily activities.

Why Does Sitting Make Lower Back Pain Worse?

Your lower back, also called the lumbar spine, supports your upper body and helps you bend, twist, and move throughout the day. When you sit, the position of your spine, pelvis, and hips changes. Different muscles and joints take on different demands compared with standing or walking.

Some people find sitting comfortable, while others find it aggravates their symptoms. There are several possible reasons for this.

1. Staying in One Position for Too Long

One challenge with prolonged sitting is the lack of movement. Your back and surrounding muscles may begin to feel stiff or uncomfortable when you remain in one position for an extended period.

You may feel fine at the start of the workday but notice increasing discomfort as the hours pass. Changing positions, standing, or walking for a few minutes may help. The goal isn't necessarily to avoid sitting, but to move regularly.

2. Your Sitting Position May Be Aggravating Your Symptoms

Leaning forward toward a computer or sitting in a rounded position for a long time can aggravate discomfort in some people. Certain positions place different demands on the muscles and structures of your lower back.

That doesn't mean occasional slouching damages your spine. There isn't one universally correct sitting position. Try finding comfortable positions and changing them rather than holding a rigid posture all day.

3. Spinal Disc Irritation

Between the bones of your spine are discs that help distribute forces during movement. Some sitting positions, especially prolonged forward bending, can increase the load placed on these discs.

If you have a disc-related condition, sitting or bending may worsen your symptoms. In some cases, nearby nerves can become irritated, leading to pain, tingling, or numbness that travels into the leg.

However, disc changes don't always cause pain. Approximately 30% of people over the age of 30 have disc-related changes without experiencing any symptoms. This means that changes found on an imaging scan don't necessarily explain someone's lower back pain.

4. Reduced Movement and Muscle Stiffness

Your lower back, hips, and surrounding muscles work together during daily activities. After a long period of sitting, these areas may feel stiff when you first stand up. This doesn't mean your muscles have permanently shortened or that you have damaged your back.

Regular walking, comfortable mobility exercises, and strength training can help you stay active and improve your tolerance for everyday movement.

5. Existing Lower Back Conditions

Sometimes sitting aggravates an underlying condition rather than being the main cause of your discomfort. Possible contributors include muscle strains, disc-related pain, sciatica, and age-related changes in the spine.

Interestingly, people with certain conditions, such as lumbar spinal stenosis, may feel better sitting and worse standing or walking. This is one reason that how your symptoms respond to different positions matters.

Why Does My Lower Back Hurt When I Stand Up After Sitting?

After a long meeting or car ride, you might need a few moments to feel comfortable when you stand up. Your back and hips may feel stiff after remaining in one position, and the transition can temporarily challenge sensitive muscles or joints.

If the discomfort gradually eases when you walk around, that is useful information for your physiotherapist. If standing causes severe pain, weakness, or symptoms that continue to worsen, seek an assessment.

Is Sitting With Bad Posture Causing Your Back Pain?

Posture often gets blamed for lower back pain, but the relationship isn't that simple. A supportive sitting position may help you feel more comfortable, but you don't need to maintain one exact posture all day.

Instead of worrying about your posture every minute, focus on practical habits:

• Choose a comfortable and supported position.

• Keep your feet supported when possible.

• Avoid awkward reaching or leaning forward for extended periods.

• Adjust your desk and chair when needed.

• Change positions regularly throughout the day.

Rather than searching for one perfect position, give yourself permission to move.

What Can You Do to Relieve Lower Back Pain From Sitting?

If your back starts aching after you've been sitting for a while, small changes to your daily routine may help.

1. Take Regular Movement Breaks

Try getting up every 30 to 60 minutes, or sooner if your back becomes uncomfortable. You don't need to complete a full workout each time.

• Walk around your home or office.

• Stand during a phone call.

• Get up to refill your water.

• Try a few gentle mobility movements.

• Alternate between sitting and standing during the day.

2. Adjust Your Workspace

If you work at a desk, your workstation setup can affect comfort. Adjust your chair so your feet are supported, use the backrest or a small lumbar cushion if helpful, keep your monitor at a comfortable height, and position your keyboard and mouse within easy reach.

An expensive chair isn't always necessary. A comfortable and adjustable setup that lets you move is often more useful.

3. Keep Moving Outside of Work

Walking, swimming, cycling, and strength training can support your overall movement capacity. A short walk after work or time on Edmonton's River Valley trails can be a simple way to add movement to your routine. Start with manageable activities and build gradually.

4. Try Gentle Lower Back Mobility Exercises

Some gentle movements may help ease stiffness after sitting. These examples aren't a personalized exercise program, so stay within a comfortable range and stop if your symptoms worsen.

Pelvic Tilts

Lie on your back with your knees bent and feet flat on the floor. Gently tilt your pelvis to flatten your lower back toward the floor, then relax and allow a comfortable arch to return.

Cat-Cow Stretch

Start on your hands and knees. Slowly round your back toward the ceiling, then gently arch in the other direction. Don't force either position.

Knee-to-Chest Stretch

Lie on your back with your knees bent. Gently bring one knee toward your chest until you feel a comfortable stretch, then change sides. This isn't appropriate for everyone, especially if bending aggravates symptoms.

If exercises cause increasing pain or symptoms that spread farther down your leg, stop and speak with a healthcare professional.

5. Build Strength Around Your Back and Hips

Stretching can help with stiffness, but strengthening is also important for many types of lower back pain. Muscles around your spine, abdomen, and hips work together when you sit, stand, lift, and walk.

Your physiotherapist may recommend exercises such as bridges, bird dogs, or other gradual strengthening movements based on your symptoms and current abilities.

Will a Standing Desk Help With Lower Back Pain?

A standing desk can be useful because it allows you to change position during your workday. However, standing all day isn't necessarily better than sitting all day.

Try alternating between sitting for focused work, standing for a phone call, and taking a short walk between tasks. The best routine is one that fits your day and helps you remain comfortable.

How Can Physiotherapy Help With Lower Back Pain From Sitting?

If you've adjusted your chair, taken movement breaks, and tried exercises but your back still hurts, physiotherapy may help. Lower back pain often has more than one contributing factor, and the same treatment doesn't work for everyone.

At Shift Physiotherapy & Wellness in Edmonton, your physiotherapist can assess your symptoms, mobility, strength, and daily activities to help develop a plan around your goals.

Understanding Your Symptoms

Your physiotherapist will ask when your pain started, what makes it better or worse, whether symptoms travel into your legs, and how pain affects work, exercise, and everyday life. They may assess spinal movement, hip mobility, muscle strength, and nerve-related symptoms.

Individualized Exercise Rehabilitation

Exercise is commonly recommended for managing lower back pain. Your physiotherapist may recommend mobility, strength, endurance, and movement exercises that start at a manageable level and progress as your symptoms improve.

Hands-On Treatment When Appropriate

Manual therapy may help manage discomfort or stiffness for some people, particularly when combined with exercise and education. It isn't necessary for everyone, and the longer-term aim is to help you manage symptoms confidently.

Practical Advice for Everyday Activities

Your physiotherapist can help with workstation adjustments, comfortable sitting options, movement breaks, and building your tolerance for longer periods of sitting.

When Should You See a Physiotherapist for Lower Back Pain?

Occasional stiffness doesn't always require treatment. Consider booking an assessment if:

• Your back pain keeps returning after sitting.

• Discomfort is interrupting your workday.

• Standing after sitting has become painful.

• Pain limits exercise or other daily activities.

• You've tried changing positions and exercising without improvement.

• You're unsure which activities are appropriate.

Seek urgent medical attention if you experience new loss of bladder or bowel control, numbness around the groin or saddle area, or significant or worsening leg weakness. Back pain with fever, unexplained weight loss, or following a significant injury also needs medical assessment.

Frequently Asked Questions About Lower Back Pain From Sitting

Why does my lower back hurt when I sit but not when I stand?

Sitting changes the position of your spine and the demands placed on muscles, joints, and discs. If certain structures are sensitive to sustained sitting, symptoms may improve when you stand or walk. An assessment can help identify contributing factors.

Can sitting all day cause lower back pain?

Prolonged sitting can aggravate lower back discomfort, particularly without regular position changes. Sitting alone, however, doesn't explain every case. Existing conditions, activity levels, and other factors may play a role.

How often should I get up if I have lower back pain?

Try moving or changing positions about every 30 to 60 minutes, or more frequently if you need to. Brief breaks may help prevent discomfort from building.

Is it better to sit or stand with lower back pain?

It depends on your symptoms. Some people feel better standing and others prefer sitting. Alternating between sitting, standing, and walking is often a practical approach.

What is the best sitting position for lower back pain?

There is no single perfect sitting position. Find a supported and comfortable posture, with your feet supported if possible, and change positions regularly.

Can sitting make sciatica worse?

Yes, sitting can aggravate sciatica in some people, particularly if nerve symptoms are sensitive to certain positions. Pain, numbness, or tingling travelling down the leg should be assessed if persistent or worsening.

What exercises help lower back pain from sitting?

Gentle mobility movements such as pelvic tilts, cat-cow, and knee-to-chest stretches may be helpful for some people. Strengthening your back and hips may also be beneficial. Choose exercises suited to your symptoms.

Can physiotherapy help with lower back pain from sitting?

Yes. Physiotherapy can help assess contributing factors and provide individualized exercise, activity modifications, and education to support function and manage symptoms.

Do I need a doctor's referral for lower back physiotherapy in Edmonton?

No. In Alberta, you can generally book directly with a physiotherapist. Some extended health insurance plans may require a referral for reimbursement.
