New pain versus long-term pain – not the same alarm

When you cut your finger, twist your knee or pull a muscle, the pain you feel in the first hours and days is usually a clear message: “Something has been harmed – please protect this area while it heals.” This is often called acute, or new, pain. It tends to fade as the tissues settle and repair.

Long-term pain behaves very differently. It can continue for months or years, even when scans look stable and the original injury should have healed. It can appear to come and go without warning, and the intensity can feel out of proportion to what you are doing. Many people are told, “We can’t see anything serious,” yet the pain they live with is very real and very draining.

The key idea is this: with long-term pain, your pain system itself can change. The alarm is not broken, but it has become over-protective.

The “volume control” – why everything feels turned up

A helpful picture for many people is to imagine that your brain and spinal cord hold a volume control for pain and other warning signals:

• New pain: the volume goes up for a short time around the injured area, then drifts back down as you heal.
• Long-term pain: the volume control can get stuck on a higher setting and starts reacting to smaller and smaller triggers.

In this sensitised state, your system may:

• Send out pain messages with less provocation – a short walk, a change in the weather, a poor night’s sleep.
• Spread the feeling more widely – pain that began in one hip now “talks” down the leg or across the back.
• Hold on to pain after an activity finishes, so you “pay for it” later in the day or the next morning.

Nothing about this means you are imagining it or “being soft”. It is your body’s protection system trying too hard – a smoke alarm that now shouts at steam from the kettle as if it were a house fire.

What actually changes inside the nervous system?

Your pain system is made up of tiny sensors in your tissues, long nerve wires, the spinal cord and your brain. When pain has been around for a long time, several subtle changes can occur:

• The sensors in joints and muscles may become more excitable, sending messages more often and at lower levels of strain.
• The spinal cord “gates” that normally filter information can let more warning signals through and send fewer “calm down” messages back down the line.
• The brain networks that read body signals can learn to expect danger in the places that have hurt for a long time.

Scientists sometimes call this central sensitisation – not because it is “in your head” in a dismissive way, but because the central nervous system has become more responsive. You could think of this as a well-meaning bodyguard who now jumps every time a door creaks, even in a safe room.

How the brain’s predictions play a role

A piece of “rare” knowledge that many people are never told is that the brain does not simply receive pain messages – it also predicts them. It constantly compares:

• What your tissues are sending up in this moment.
• What has happened in this body area before (injuries, surgeries, painful flares).
• What the situation feels like now (stress, worries, memories, the time of day, who you are with).

If that pattern “feels like” previous danger, the brain may decide, often outside of your awareness, that it is safer to create a strong pain response early. Over months and years, the prediction itself can become faster than the actual tissue change – almost like a learned body memory.

This is one reason why a simple activity, such as walking past the spot where you once fell, or standing at a sink where you often struggle, can trigger pain before you have done very much at all. Your system is trying to stay one step ahead of harm.

Why flare-ups happen even when you “haven’t done anything”

Many people with long-term pain describe bad days that seem to come out of nowhere. You wake up feeling stiff and sore, or your usual background ache has suddenly turned into a sharp, consuming flare. On paper, nothing particular has changed.

Often, what has changed is the overall load on your nervous system, not a single movement or event. Subtle factors can add up, such as:

• Poor or broken sleep over several nights in a row.
• Fighting off a cold or infection, even a mild one.
• Ongoing worry about money, housing, family or health tests.
• Being less active for a few days, so joints and muscles become stiffer and more guarded.
• Feeling alone with the pain and watching it closely, minute by minute.

Your nervous system does not separate these into “stress”, “illness” and “movement”. It simply asks, “Do I feel under threat?” If the answer is yes, the volume control can turn up temporarily, even if you spent most of the day sitting quietly.

Body position and environment – small but powerful signals

Over time, your system can also attach meaning to particular postures and environments:

• A certain chair that you associate with hours of pain and boredom.
• A dark, cluttered hallway where you once lost your balance.
• Hard kitchen worktops that make you tense your shoulders without noticing.

These become part of the “story” your nervous system tells itself. Changing the environment even slightly – better lighting, safer footwear, a supportive cushion, a more stable chair – does not magically cure pain, but it does send a quiet message of safety that, repeated often, can help ease the volume over time.

What helps a sensitised system to settle?

There is no single trick that switches long-term pain off. However, small, repeated signals of safety can gradually nudge the volume control down. These usually work best when combined with your health team’s advice on medicines, injections or surgery where appropriate.

• Understanding what is happening. When you realise that flare-ups are often your alarm system over-reacting, rather than fresh damage every time, it can reduce panic and fear – two fuels that strongly drive pain.
• Gentle, regular movement. Short walks indoors, simple chair-based exercises or our PHAT Zoom sessions can remind the nervous system that movement and safety can exist together.
• Calming the “background noise”. Simple breathing exercises, listening to music you enjoy, or brief relaxation exercises before bed can help soften the overall load on your system, even if they do not remove pain completely.
• Breaking the all-or-nothing pattern. Doing a tiny amount most days, instead of doing nothing for a week then over-doing it on a “good” day, gives the nervous system steadier, more predictable input.
• Staying connected. A short phone call, a group session or a familiar face on Zoom can reduce the loneliness that often makes pain feel louder.

None of these steps mean you should ignore serious new symptoms. They are about calming an over-alert system, not about pushing through worrying pain without help.

How PHAT sessions fit into this picture

Our gentle group sessions are designed with long-term pain in mind. The movements are deliberately steady and adjustable, so you can explore what your body can manage today rather than what you “used to do years ago”. The social contact, routine and shared understanding are just as important as the exercises themselves.

Over time, many people find that:

• Their body becomes less fearful of small movements.
• They recover from short activities more quickly, even if bad days still occur.
• They feel a little more in charge of the story of their pain, rather than waiting helplessly for the next flare-up.

Long-term pain may not disappear, but your relationship with it can change. Your nervous system is capable of learning in both directions – into sensitisation, and gradually back towards balance.
