We all experience pain from time to time. Sometimes it comes on suddenly and settles within a few days. Other times, it seems to hang around, or keeps coming back.
So, what is the difference between acute and chronic pain?
Put simply, acute pain is generally short-term pain, lasting less than three months. Chronic, or persistent, pain is pain that lasts or keeps recurring for more than three months. These are the commonly used clinical timeframes, although pain doesn’t suddenly change overnight when it reaches three months. There is a little more to it than simply counting the weeks and months, as you will find out now.
What is acute pain?
Acute pain is generally pain that has started relatively recently. It is often your body’s way of saying, “Something isn’t quite right here – let’s take a bit of care.” For example, you might develop back pain after lifting something, strain a muscle during exercise, or wake up with a stiff and painful neck. In this sense, acute pain can be protective. It encourages us to change what we’re doing, take some care and give things time to settle. Often, acute pain reduces as the initial problem recovers.

What about chronic or persistent pain?
Pain that lasts or keeps recurring for more than three months is generally described as chronic or persistent pain. I tend to prefer the word persistent, as “chronic” can sometimes sound as though the problem is permanent. It doesn’t necessarily mean that.
When pain continues for longer than expected, the nervous system can become more sensitive to signals from the body. This is sometimes described as increased sensitivity or sensitisation. This can mean that pain continues even after the original irritation has settled. That doesn’t mean the pain isn’t real – it absolutely is. It simply means that the pain doesn’t always tell us exactly what is happening in the tissues at that moment.
Why does pain sometimes stick around?
Pain is a complicated experience. Alongside what is happening physically, things such as sleep, stress, fatigue, previous experiences of pain, activity levels and how confident we feel about moving can all influence how we experience it.
Think of it a little like an alarm system.
An alarm is there to protect us, but sometimes it can become more sensitive and respond to things that it wouldn’t have reacted to before. Our pain system can behave in a similar way. It isn’t necessarily broken – it is trying to protect us – but sometimes it can become a little more protective than is needed.
Can you have both acute and chronic pain?
Absolutely! Someone may have experienced back pain on and off for several years, but then have a sudden flare-up after spending the weekend gardening.
The flare-up is recent, so it can be described as acute, while the underlying problem is persistent. This is why I don’t think of acute and chronic pain as two completely separate boxes. Pain can change, fluctuate and sometimes return after a period of being settled.
The important thing to remember
Acute pain is often a short-term protective response, whereas persistent pain can involve a nervous system that has become more sensitive over time.
Neither necessarily tells us how serious a problem is.
Understanding a little more about how pain works can help us make sense of our symptoms – particularly when pain has been around for a while – and can sometimes make it feel a little less worrying.
So, where does osteopathy fit in?
Whether your pain is recent or something you’ve been managing for a while, an osteopathic assessment can help to understand your symptoms, how they are affecting your movement and day-to-day activities, and what might be contributing to them.
Treatment and advice can then be tailored to you, whether you’re dealing with a new episode of pain or a longer-term problem. The aim is to help you manage your symptoms, improve your movement and get you back to the things that matter to you.
