According to the Institute of Medicine (2011), pain is a critical indicator of inflammation and can significantly impact quality of life. Cases such as arthritis demonstrate how chronic inflammation can lead to persistent pain.
Swelling: Swelling, or edema, develops when excess fluid accumulates in tissues. The National Institutes of Health (NIH) notes that swelling often results from increased blood flow and immune cell migration to the injury site. In conditions such as an ankle sprain, localized swelling can become evident within hours after trauma.
Redness: Redness, or erythema, manifests due to increased blood flow to the inflamed area. The visible redness results from the dilation of blood vessels (vasodilation). The American College of Rheumatology states that redness can be prominent in inflammatory responses, such as in skin infections or inflammatory skin conditions.
Heat: Heat occurs due to increased blood flow and metabolic activity in the inflamed area. The body’s immune response increases temperature in localized areas, creating an environment less favorable for pathogens. Fever can also present in systemic inflammation, reflecting the body’s attempt to fight off infections.
Loss of Function: Loss of function refers to decreased ability to use the inflamed area. This sign can vary in severity depending on the extent of the inflammation. For example, in conditions like tendonitis, the affected limb may experience reduced mobility or strength. This concept is further supported by the World Health Organization, which emphasizes that functionality is crucial in assessing health outcomes.

In summary, recognizing and understanding the signs of inflammation or other abnormalities can aid in early intervention and treatment.
