Why does my lower back pain go away when sitting?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Lower back pain often improves when sitting because this position reduces pressure on specific spinal structures. Sitting slightly flexes the lumbar spine, which can widen the spinal canal and relieve nerve compression—a hallmark of conditions like lumbar spinal stenosis. In contrast, standing or walking extends the spine, narrowing these spaces and triggering pain. Other causes, such as facet joint arthritis or muscle strain, may also feel better with sitting due to decreased load on the lower back muscles and joints.

However, pain that shifts with position can signal several different underlying issues, from mechanical strain to nerve-related conditions. Understanding the specific cause is the first step toward effective relief. Take a free, instant, AI-powered symptom check to explore what may be driving your back pain and get personalized guidance on the best next steps.

Explanation

When you sit down, the position can help reduce pressure on your spine. This is because sitting can open up spaces in the spine that might be narrowed, especially if you have a condition like spinal stenosis.

How Sitting Helps:

Spinal Stenosis: Spinal stenosis is a condition where the spaces in the spine get smaller, putting pressure on the nerves. Sitting can help by opening up these spaces, which might reduce pain.
Discogenic Pain: Some back pain comes from the discs between the bones in your spine. Sitting can change the pressure on these discs, sometimes making the pain better.
Position Change: Simply changing positions can sometimes help relieve pain, as it gives different parts of your back a break from pressure.

It's important to remember that if you have ongoing back pain, it's a good idea to use a symptom checker to better understand what might be causing your discomfort and determine the best next steps for care.
