Inflammatory Response:
Symptoms and Causes

Inflammatory response is a physical response with the most common symptoms being redness, irritation, itchiness, swelling, pain, and rise in temperature.  It is caused by our immune system when it detects a pathogen, dangerous substance, or injury.

While it may cause a lot of discomfort, it is how your body protects itself from pathogens or injury.

Additional Information


Injury can be caused by pathogens, harmful chemicals (such as strong acid), or outside forces (such as a rock hitting your head).


Pathogens are micro-organisms that can cause an illness and are contagious, capable of spread from person-to-person.

Temperature Increase

A temperature increase can manifest itself to different parts of the body.  When it happens to our head, we call it a “fever”.  When it happens to other parts of the body, such as a sprained ankle, you may simply notice your injured ankle feeling warm to the touch.
