"I haven't done very much today, but I'm completely exhausted."

This is something I hear almost every day in clinic.

Many people living with persistent pain worry that others think they're lazy, unfit or simply not trying hard enough.

But living with chronic pain is hard work.

Not just because it hurts.

Because your brain is working overtime every waking minute.

Pain is never just pain

When most people think about pain, they imagine the physical sensation.

But persistent pain affects almost every part of your day.

Before getting out of bed, you may already be thinking:

"How bad is today going to be?"

"Can I manage the school run?"

"Will I cope with work?"

"Should I cancel dinner tonight?"

These aren't dramatic thoughts.

They're practical decisions that many people with pain make every single day.

Each one takes mental energy.

Every activity becomes a calculation

Most people don't think about climbing the stairs.

Or carrying the shopping.

Or standing to cook dinner.

When you live with chronic pain, however, almost everything involves planning.

You begin weighing up every decision.

"If I vacuum the house this morning, will I still be able to walk the dog later?"

"If I go to my granddaughter's birthday, will I spend the next two days recovering?"

"Should I save my energy for work tomorrow?"

It's like managing a bank account where your energy is limited.

Every activity has a cost.

Your brain never really gets a day off

Your nervous system is constantly processing information.

Where does it hurt?

Has the pain changed?

Can I sit more comfortably?

Would walking help?

Should I take medication now or wait?

Why is my shoulder hurting today?

Most of these thoughts happen automatically.

But they still require attention.

Imagine trying to work while someone taps you on the shoulder every few seconds.

Eventually, even if each interruption is small, you become mentally exhausted.

Persistent pain can feel very much like that.

The invisible backpack

Imagine carrying a heavy backpack.

At first, you hardly notice it.

As the hours pass, however, your shoulders begin to ache.

Your back becomes sore.

Everything feels harder.

Now imagine that nobody else can see the backpack.

They simply wonder why you're walking more slowly.

Persistent pain often feels like carrying an invisible weight.

Other people may only see you walking into the supermarket.

They don't see everything you've already carried before you arrived.

It's not just pain you're carrying

Many people with chronic pain are also carrying:

• Poor sleep

• Fatigue

• Worry about the future

• Frustration

• Medication side effects

• Family responsibilities

• Financial concerns

• The effort of trying to appear "normal"

None of these may be visible.

Yet together they create an enormous emotional and physical load.

Decision fatigue

One of the least recognised effects of persistent pain is something called decision fatigue.

By the end of the day you've made hundreds of tiny decisions about your pain.

Should I sit?

Stand?

Stretch?

Rest?

Push on?

Take medication?

Cancel my plans?

Ask for help?

Every decision uses a little mental energy.

Over time, that becomes exhausting.

Why people stop socialising

Friends sometimes assume people with chronic pain simply lose interest.

Usually the opposite is true.

Many desperately want to join in.

But every outing comes with calculations.

Where can I park?

Will there be somewhere to sit?

How long will I manage?

What happens if I have a flare?

Will people understand if I leave early?

Sometimes staying at home isn't what someone wants.

It's simply what feels manageable.

Be kind to yourself

Living with persistent pain requires remarkable resilience.

You are adapting.

Planning.

Problem-solving.

Managing uncertainty.

Every single day.

If you feel tired, it doesn't mean you're weak.

It doesn't mean you're failing.

It may simply mean you've been carrying an invisible load for a very long time.

A final thought

When someone is carrying heavy shopping bags, we don't criticise them for walking slowly.

We recognise that they're carrying something difficult.

Persistent pain is much the same.

The load may be invisible.

But that doesn't make it any less real.

Perhaps today is a good day to acknowledge just how much you've been carrying.

And perhaps it's also a good day to let someone help you put a few of those bags down.
