Best explanation to how does pain occur?

Overview

How does pain occur: Some things just occur and we experience them without much knowledge about them.  Including the things that happens on our bodies. We feel pain and we know what to do but not  exactly what has taken place for us to feel it, of course the cause maybe well known.

Pain is one of  the most common  complaints patients come with in hospital visits. Yes most clinicians will agree with me.And that is why we ask a lot of questions trying to find out what the cause of your pain might be.

Defining pain is something tricky. Hence pain is what you say it is, there is no specific definition.  We may say pain is a hurtful sensation to your body. But look is that specific? No.

For pain to be felt we have what is called nervous system in our bodies. The nervous system acts as the network (signal transmission system). It carry information from one end to the other for interpretation by the brain and the spinal cord.

The same way if a network cable is cut, nerve cutting or damage  will lead into loss of sensation or whatever the function of that nerve fiber.

Today I will explain step by step about everything that happens for you to feel pain.i will make sure I reduce the medical terms to as low as 12th grade level for everyone’s understanding.

Pain perception, or nociception (from the Latin word for “hurt”), is the process by which a painful stimulus is relayed from the site of stimulation to the central nervous system. There are several steps in the nociception process There are Merely 4 things  that happens for you to feel pain:

i.e

1.Contact with the stimulus(hot object, sharp thing, etc),

2.Reception

3.Transmission

4 .Reception in the brain.

Here is What happens for you to feel pain?

  • Contact with stimulus— Stimuli can be mechanical (pressure, punctures and cuts) or chemical (burns).

Like I said earlier stimulus is anything that can trigger pain for this purpose. You can think of a knife that can cut you, needle that can prick you, fire or hot thing that can burn you are all examples of stimuli. That is just an example list of stimuli but can be many things that cause pain.  For the pain to occur you need one of them. Once you come into contact with any of it, the nervous system starts working processing the signal to intended  destination (brain).

  • Reception— A nerve ending senses the stimulus.

After a contact with the stimulus the nerve endings detects/senses it. Nerve endings have special receptors that receive different sensations and they also produce chemicals that will transport the signal of that sensation to other parts of the nervous system. Those chemicals are called neurotransmitters.

The receptors responsible for pain-signal reception are called nociceptors (hurt receivers). Here things are specific because for pressure that is not hurtful the receptors responsible will be baroreceptors and not the nociceptors. unless that stimulus cause pain, nociceptors won’t work.

  • Transmission— A nerve sends the signal to the central nervous system. The relay of information usually involves several neurons within the central nervous system. Here between the nerve tracks are gaps and the neurotransmitters work to carry information from one nerve to the other till to brain.

  • Pain center reception— The brain receives the information for further processing and action. Not until the brain receives such signals and interprets will you feel any pain. After processing of pain the brain will further generate an action needed for protection. You know the whole of this process is to make sure the body parts are protected from further injury. So, the brain will send a signal for withdrawal of your hand in case you touch a hot object. Same if you step on a prickly thing or anything hurtful the same action by the bran will be sent so you remove your leg. The signal generated by the brain for motor action will travel back to the part involved to release the stimulus.how does pain occur
