Sterile inflammation is an inflammatory response in the body caused by non-bacterial (e.g., physical, chemical, etc.) factors, which can present with symptoms such as redness, swelling, heat, pain, or dysfunction. Inflammation is a defense reaction that occurs in living tissues with a vascular system (e.g., the body) to injury factors, and can be divided into infectious inflammation and aseptic inflammation. Infectious inflammation has bacterial, viral and other infections; in sterile inflammation, there is no bacterial infection at the site that causes the inflammatory response. Aseptic inflammation should seek timely medical attention to identify the cause of inflammation, different causes should take different treatment measures, should actively treat the primary disease, under the guidance of the doctor to take medication, so as not to delay the condition.
