Your pain doesn't persist because you haven't stretched enough.
It persists because traditional mattresses force your spine to curve into an unnatural position for hours every night, squeezing your discs dry.
Think of your spinal discs like sponges.
During the day, they stay hydrated and cushion your nerves.
But at night, your spine loses its natural curve. Your lumbar lordosis flattens and the pressure on your sciatic nerve increases with every hour you lie there.
And those discs, hour after hour, get compressed. Squeezed dry.
And when a disc gets compressed night after night, it doesn't just dehydrate, it starts to bulge outward.
Like a sponge that's been squeezed so many times, it loses its shape.
Doctors call this a herniated disc.
And once it bulges, it pushes directly into your sciatic nerve, the longest nerve in your body, running from your lower back all the way down to your foot. Trapped.
No way out.
And that's the shooting pain. That's why you toss and turn at night. That's why mornings are unbearable.
Physiotherapy tries to heal a nerve being crushed by a dried-out disc every single night.
But you can't heal what's being destroyed faster than it can recover.
"They've been thinking about this backwards for three decades," Dr. Spencer explained.
"Instead of preventing the collapse, they've been trying to heal the nerve while it's still being crushed."
This explains why you might have perfect physio compliance but still wake up in agony.
Your body knows something is wrong.
That's why you shift positions dozens of times during sleep.
Your nervous system is trying to find natural positioning that releases pressure on the nerve.
But there isn't one. Not with a collapsing spine.
"People who 'fail' at physiotherapy aren't non-compliant," Dr. Spencer realized.
"They're responding to basic survival instinct."
