When you sit for extended periods, especially with poor posture, it can put extra pressure on your lower back and sciatic nerve.
This prolonged pressure can lead to a pinched nerve, causing pain that radiates from your back down to your legs.
People who sit a lot might feel like they have a pinched nerve on their hip, but it's usually the sciatic nerve being irritated near the spine.
The unnatural position of sitting for hours can put a lot of pressure on your legs, leading to leg pain, numbness, or tingling sensations.
