We all feel pain from time to time. When someone injures themselves, specific nerves recognise this as pain, which in turn triggers the body’s repair mechanism. As the problem resolves, the pain tends to improve and usually disappears within 3-6 months. This type of pain could be argued to be beneficial: if it hurts, you are likely to try and avoid doing whatever it is that has caused the pain in the future, so you are less likely to injure yourself in that way again.

Occasionally the pain continues even after tissue healing has finished. When pain continues after this point, it becomes known as persistent (or is sometimes referred to as chronic) pain. This type of pain is not beneficial and is a result of the nerves becoming over-sensitised, which means that a painful response will be triggered much more easily than normal. This can be unpleasant, but doesn’t necessarily mean that you are doing yourself any harm simply by moving. You could think of this as a sensitive car alarm that goes off in error when someone walks past (for more information on how pain works, visit: https://www.youtube.com/watch?v=QUrKgv43W2c ).
