What causes Pain?

Various daily activities and actions may cause pain and aches. For example, a pinch from someone or engaging in strenuous exercises that can lead to muscle aches. Occasionally, pain also occurs through serious injuries and illnesses such as road accidents and sore throats.

Cytokines, a type of protein found in the nervous system, also part of the body's immune system and the body's shield for fighting off disease can also trigger pain. It promotes inflammation even in the absence of injury or damage. Certain types of cytokines have been linked to nervous system injury. After trauma, cytokine levels rise in the brain, spinal cord and at the site in the peripheral nervous system where the injury occurred. Below is a picture of cytokines.
