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

You’ve been sitting at your desk, driving in the car, or relaxing on the couch. Then you stand up and your lower back suddenly feels stiff, achy, or like it takes a few steps before you can completely straighten up.

Sound familiar? Sitting for an extended period can affect the muscles and joints around your lower back, hips, and pelvis. The good news is that some simple changes may help.

Why Does It Happen?

Your body is designed to move, and staying in one position for a long time can contribute to stiffness. While you’re sitting, your hips remain flexed and some of the muscles around your hips and lower back stay in shortened or relatively inactive positions.

When you stand, those muscles and joints have to transition quickly back to an upright position. That’s often when you notice the stiffness or discomfort.

How you sit matters, too. Slouching, leaning to one side, crossing your legs for long periods, or sitting with a wallet or other object in your back pocket can create an uneven position through your pelvis and lower back.

Even good posture isn’t meant to be held indefinitely. Changing positions regularly is often more important than trying to maintain one “perfect” posture all day.

Your Hips and Core Matter, Too

Your lower back doesn’t work by itself. Your hips, pelvis, abdominal muscles, and back muscles all work together as you sit, stand, and walk.

That’s one reason your movement patterns can provide useful information about how your body is functioning. Our article What Your Walk Says About Your Spine explains more about the relationship between walking mechanics and the spine.

Your core muscles also help support and stabilize your spine during everyday activities. Learn more in The Role Your Core Muscles Play in Protecting Your Spine.

What Can You Do?

If your back tends to feel stiff when you first stand up, try:

• Getting up and moving periodically during long periods of sitting.
• Changing your sitting position throughout the day.
• Making sure your chair and workstation allow you to sit comfortably without constantly leaning or twisting.
• Staying physically active to maintain strength and mobility.
• Paying attention to patterns. Does it happen after driving, working at your desk, or sitting on a particular chair or couch?

When Should You Have It Checked?

Occasional stiffness is different from pain that happens every time you stand, is becoming more frequent, or interferes with your normal activities.

Back pain can have many causes, so an evaluation can help determine whether joint mobility, muscle tension, movement patterns, or another problem may be contributing.

At Affinity Chiropractic, Dr. Jane Bigby uses the Activator Method, a gentle, low-force technique that doesn’t require twisting or cracking. Learn more about our chiropractic care in Klamath Falls and how we approach back pain and mobility concerns.

If sitting comfortably is easy but getting back up isn’t, it may be time to find out why.
