Lucy explains pain.
Pain is a process which is controlled by the nervous system. It is there to protect us from danger and/or injury. Sometimes in cases such as CRPS and Fibromyalgia this pattern can get confused.
Pain is there to communicate there is something wrong. The pain receptors are all over our body in our nerves and when we feel pain it sends a signal up to the brain so the brain can try to help us out for example, swelling. Our joints can swell to create a protective cushion to try to prevent further damage to the affected area to allow it to heal efficiently.
The nervous system is made up of the brain, the spinal cord and nerves. These parts all communicate with each other by sending messages these ‘messengers’ are called neurotransmitters. Neurotransmitters communicate lots of different messages but in the case of acute pain when we touch a hot surface the nerve cells (also known as a neuron) pick up there is an abnormality. This process correlates well with acute pain. Acute pain settles when the injury has healed, however chronic pain persists.
The neurotransmitter, known as the pain receptors in the case of pain, sends a signal to the brain through the nerves up in the spinal cord to the part of the brain which deals with pain. The brain can also send endorphins which are natural pain relievers. The brain then sends down a response to the affected area creating pain to make us aware there is something happening and gives us a response in order to prevent damage/injury/relief the pain, in acute pain, with the example of burning your hand on a hob, removing your hand from the hot surface would be the first line of resolution your brain would tell your body to do.
