Symptom #2: Swelling
When an injury occurs, swelling is often a common sequela due to accumulation of fluid. When an injury occurs, there is tissue damage, causing the release of bradykinin and histamine. This leads to dilation of the blood vessels, which allows more blood to reach the injured area. Inflammation has a protective function.
When bradykinin and histamine are released, pain signals are sent to the brain. This results in the individual realizing that an injury has occurred, and rest or attention is needed to the region to allow healing. The inflammatory mediators also allow immune system cells and fluid to easily pass through the vessels resulting in swelling. Swelling usually resolves once fluid is transported out of the tissue.
