Why do I experience lower back pain when standing up after sitting?

When you sit for a long time and then stand up, your lower back might hurt because your spine and muscles need to adjust.

Spine Curve Changes:

• Sitting and standing change the curve of your lower back, called lumbar lordosis. This change can make your back feel uncomfortable when you stand up.

Muscle Activity:

• When you move from sitting to standing, your muscles must work in a certain way. If they don't work right, it can cause pain.

Pressure in the Spine:

• The pressure inside your spine is different when you sit and stand. This pressure change can also make your back hurt.

By understanding these reasons, you can see why your back might hurt when you stand up after sitting for a while. It's important to move and stretch to help your back feel better.
