What are common signs of inflammation?

Redness, heat, swelling, and pain are hallmark signs of inflammation. When tissue is damaged, whether due to injury, infection, or other factors, the body's immune response is activated. This response includes increased blood flow to the affected area, which results in redness and heat. The accumulation of fluids and immune cells causes swelling, as the body works to repair the tissue and fight off any potential pathogens. Pain is also a significant symptom that arises due to the release of chemicals that stimulate nerve endings, alerting the body to the injury and encouraging protective behaviors that limit further damage. Understanding these signs is crucial in sports medicine for identifying injuries and guiding treatment protocols effectively. Other options, such as increased energy levels, improved range of motion, and high blood pressure, do not typically indicate inflammation and can reflect other physiological conditions that aren't directly related to the inflammation process.
