“Why Does My Sciatica Keep Coming Back?”
If you’re over 40, work at a desk, and feel a shooting pain down your leg, you might be dealing with sciatica — and your sedentary lifestyle may be the root cause.
Here’s the uncomfortable truth. Most people don’t realise their sciatica pain is linked to muscle wasting and long hours of sitting.
Desk Jobs & Nerve Compression
The human body wasn’t made to sit for 8+ hours. Over time, this leads to:
Tight hip flexors
Weak glutes
Overworked lower back
Poor posture and spinal alignment
This environment compresses spinal discs and irritates the sciatic nerve, especially at the L4-L5 or L5-S1 vertebrae.
📊 A 2022 study in the journal “Healthcare” found that a sedentary lifestyle increases the risk of sciatica and disc herniation by 50%+.
The Muscle Loss Problem
After age 30, we lose 3–8% of muscle per decade — a process called sarcopenia. If you’re not actively strength training, your core and glutes weaken, leading to:
Reduced spinal support
Pelvic misalignment
Greater nerve compression
Muscle isn’t just for looks — it’s essential for pain-free movement, spinal protection, and nerve health.
