Why does my back hurt more after sitting for long periods?

Prolonged sitting can increase spinal loading and reduce movement variety, which often leads to stiffness and discomfort when you stand or start moving again.

Should I see a chiropractor for back pain that started without an injury?

If back pain persists, keeps recurring, or limits activity, a chiropractor can evaluate movement patterns and spinal mechanics that may be contributing—even when there wasn’t a single obvious injury.

When is back pain a sign of something more serious?

Seek urgent medical evaluation if back pain is accompanied by progressive leg weakness, bowel or bladder changes, fever, unexplained weight loss, or major trauma.

Why does my back feel worse in the morning?

Many people feel stiffer in the morning because the spine has been relatively still overnight. Getting up and moving often helps tissues warm up and joints move more freely.

Can spinal decompression help even if I didn’t lift anything heavy?

Some people benefit from decompression when symptoms relate to spinal loading intolerance. Whether it’s appropriate depends on exam findings and symptom patterns, not only on a heavy-lifting injury.

Back Pain With No Clear Injury | Chiropractor in Olathe

It’s a frustrating question I hear often in my Olathe chiropractic office: “Why does my back hurt when I didn’t do anything?” You didn’t fall, lift something heavy, or twist the wrong way—yet your back feels stiff, sore, or painful. In many cases, back pain isn’t caused by a single event but by how stress accumulates in the spine over time. If your symptoms involve your neck, upper back, or lower back, our condition pages on neck pain, headaches, upper-back pain, and low back pain explain those areas in more depth and serve as the primary clinical resources they deserve.

Back pain without a clear injury often develops when spinal joints, discs, muscles, and nerves are exposed to repeated low-level stress. Poor posture, prolonged sitting, limited movement variety, and cumulative loading can irritate tissues even when no single incident stands out.

When you look at how the spine functions day to day, this starts to make sense. Your spinal joints rely on regular motion to stay lubricated and balanced. Discs respond to compression and unloading throughout the day. Muscles stabilize posture for hours at a time, especially during sitting or screen use. Over time, uneven loading, sustained positions, or subtle movement restrictions can overwhelm the system. This is why people often wake up stiff, feel worse after sitting, or notice pain appear “out of nowhere” despite no obvious trigger. For many patients, this pattern aligns with what we see on our low back pain page, where cumulative stress plays a major role.

Patients describe a wide range of symptoms when this happens. Some notice a dull ache that lingers all day. Others feel sharp pain when standing up after sitting. Morning stiffness that eases with movement is common, as is soreness that builds as the day goes on. Some people feel tightness across the lower back, others along one side. Pain may worsen with bending, twisting, or prolonged standing, or feel better temporarily with heat or gentle movement. Occasionally, discomfort spreads into the hips, mid-back, or even upward toward the neck without following a clear pattern.

Clinically, there are recognizable patterns I see in the office. Pain that worsens after sitting but improves once moving suggests joint or disc loading intolerance. Pain that increases with repeated bending often points toward irritated spinal structures rather than muscle strain alone. Some patients tolerate standing well but struggle with prolonged driving. Others feel fine during the day but flare up at night or first thing in the morning. These patterns help guide care without turning a blog into a diagnostic page.

FAQs patients often ask:

Can stress alone cause back pain?
Stress can increase muscle tension and alter posture, which may contribute to spinal discomfort over time, especially when combined with prolonged sitting.

Why does my back hurt more in the morning?
During sleep, spinal tissues absorb fluid and stiffen. Limited movement overnight can make joints feel restricted when you first get up.

Is it normal for pain to start days after activity?
Yes. Repetitive or unfamiliar activity can irritate spinal tissues, with symptoms appearing later rather than immediately.

Could this be coming from my posture at work?
Workstation posture and prolonged sitting are common contributors to back pain that develops without a clear injury.

Should I wait it out if I didn’t injure myself?
Persistent or worsening pain is a sign that something isn’t tolerating load well and shouldn’t be ignored.
