Your Nerve Isn't Trapped — Here's What Is Going On
Your nerve isn't trapped. I know that's what everyone says — "I've got a trapped nerve in my neck" — but nerves don't get trapped, not really, not like people picture it. And that matters, because if you think something's trapped, you start thinking it needs to be clicked back into place or untrapped. That's where people go wrong.
Let me tell you what's actually happening, and then the thing that really changes your recovery — because I've seen people have ten sessions and get nowhere, and others get fixed in ten minutes. Stay with me for that bit.
My name's Joe. I'm an ex-professional football head physio and multi-clinic owner here in the UK. As always, this is a guide to help you understand what's going on. It's not a diagnosis.
Why Nerves Don't Actually Get "Trapped"
The nerve isn't trapped. It's being compromised, and that happens in one of three ways.
Compression is the first. Something is pressing on it — a disc bulge in your neck, for example, pressing on the nerve as it comes out. That's a genuine compression.
Irritation is the second, and it's more common. The nerve is being wound up by what's around it — inflammation, tight structures — and it gets oversensitised and a little bit angry.
Adhesions are the third, and this is the one people never really hear about. The nerve is supposed to glide through the tissues around it. It's supposed to slide and move as you move your arm and neck — it's not a fixed cable. If the tissue around the nerve gets sticky, tethered, or stuck to it, the nerve can't glide properly anymore. Every time you move, it's getting tugged and pulled instead of sliding freely. And that gives you exactly the same symptoms: the pain, the pins and needles, the numbness down the arm.
Compression, irritation, or adhesions restricting how it moves — any of those compromise the nerve, and any of those can give you what people call a trapped nerve. But nothing is actually trapped. That's the point. Nothing needs to be clicked or popped back into place. The nerve is being compromised somewhere — tethered, irritated, not quite gliding as well as it should. Our job as physios is to find out where, and take the pressure off it.
Why Finding WHERE Matters More Than Any Treatment
This is the bit that actually decides whether you get better. The whole game is working out where that nerve has been compromised, because it can be anywhere along its route. It might be at the back of the neck, where the nerve comes out. It might be around the collar bone. It might be in the shoulder. It might be further down the arm.
And here's why that matters so much. You can treat the wrong area for six sessions, maybe even ten, with really good hands-on treatment from a skilful therapist, and it won't change your pain at all — because you're treating a bit of the chain where there was never actually a problem. Treat the right bit, the actual place where the nerve is being compromised, and it changes almost instantaneously. Ten minutes on the right area, and the arm pain begins to settle straight away.
Why Ten Sessions Can Fail And Ten Minutes Can Fix It
I've seen it so many times in clinic. Same patient, same symptoms — the difference is just whether you're working on the right part of the chain or not.
When people tell me they've had loads of physio and it hasn't worked, and maybe they've had an MRI scan that showed nothing significant, very often this is what's happened. The treatment wasn't bad. It just wasn't aimed at the right place. And I'll be honest with you: this is where the assessment matters far more than the treatment. Anybody can rub a neck. The skill is knowing where along the whole chain the nerve is actually getting caught. That's what you're paying your money for, and that's what makes the difference.
What This Means For Your Recovery
Nerves don't get trapped. They get compromised — compressed, irritated, or stuck down with adhesions so they can't glide properly. Any of that will give you nerve pain down the arm, and that's what people are calling a trapped nerve. Nothing needs untrapping. Nothing needs clicking back into place.
What needs to happen is finding where along that nerve it's being compromised, and taking the pressure off it so it can glide and move more freely. Get that right, and it can change very quickly. Get it wrong, and you can have all the treatment in the world and stay exactly where you are.
