That Orange Line Is
Your Sciatic Nerve

If you sleep on your side, this is happening every single night. Three years before anyone told me.

The story

Last winter I started saying no to things.

The drive to see the grandkids. Getting down on the floor to play, because I knew what getting back up would cost me.

What I didn't know โ€” for three whole years โ€” was the reason why.

My hip and lower back had been at me every single morning. I'd wake with my outer hip throbbing, and those first few steps to the bathroom I'd have to hold the wall. I'd tried everything the usual way. Physios, chiros, a thousand-dollar mattress. Every one of them had a next appointment to book. Nobody had anything that lasted longer than a fortnight.

What I could never work out was why it was worst first thing in the morning. Eight hours of rest and I'd wake up feeling like I'd been hit by a bus.

That was the detail that never added up. Eight hours of rest should ease an ache, not deepen it. It turned out to be the whole answer, hiding in plain sight, in the one place nobody had thought to look. Four specialists walked straight past it. A stranger under a post didn't.

The explanation

Turns out the stranger was a physio. And what they said was almost too simple.

โšก What is actually happening

When you sleep on your side, your top knee drops toward the mattress and rotates your pelvis out of line โ€” pinching the nerve that runs from your lower back through your hip and down your leg. For hours. Every night. That's why it's worse in the morning. It's been building while you sleep.

This is the nerve the physio meant. On a side sleeper the top knee drops and the pelvis rotates โ€” right where the line is brightest. That is the spot that has been aching every morning.

Three years. Four specialists. Not one had told me the simplest thing: the position I'd slept in my whole life was doing it.

๐Ÿงก Where your sciatic nerve goes
Lower spine โ€” exits between the lumbar vertebrae
Deep buttock โ€” passes through the piriformis muscle
Back of the thigh โ€” that burning shooting feeling
Behind the knee โ€” splits into two branches
Down to the foot โ€” why it aches all the way to your toes

When your knee drops during sleep it rotates the pelvis and compresses that pathway. Not for a moment. For the entire night. Which is exactly why you wake up worse than you went to bed.

And that was the part that finally made sense of it. Wear and tear eases when you rest it. Mine got worse the longer I lay still, which meant it was never really damage. It was position. The one thing on that whole list of treatments I could actually change without booking another appointment.

The nerve is not the problem. Something is pressing on it while you sleep. Remove the pressure โ€” change the morning.

The fix

The fix wasn't another treatment.

It was just keeping my knees stacked and my hips level through the night so that nerve stops getting squeezed.

An ordinary pillow was on the floor within the hour. Useless for someone who moves around. Then I found one made for exactly that โ€” contoured memory foam with a strap around the leg so it stays put no matter how much you roll.

This is the one. The reason I am even writing this.

So look at that orange line again. If you wake up stiffer than you went to bed โ€” it might not be your age, or your mattress. It might just be the way you've always slept.

๐ŸŒ™ First night

I braced for it to slide off when I turned over. It didn't move. I woke before the alarm and lay there waiting for the throb. It wasn't there. By the end of the second week the outer hip pain when I first stood up โ€” the thing I'd had every single morning for three years โ€” was gone.
