Which of the following is NOT a sign of inflammation?

Ringing in the ears, also known as tinnitus, is not a typical sign of inflammation. Inflammation is characterized by specific signs that include swelling, redness, heat, and pain. These signs occur as part of the body’s response to injury or infection, as the immune system increases blood flow and immune activity to the affected area.

Swelling results from fluid accumulation as blood vessels become more permeable. Redness occurs due to increased blood flow (hyperemia) to the area. Pain is often associated with the release of inflammatory mediators that stimulate nerve endings. Tinnitus, on the other hand, is related to auditory system issues rather than the inflammatory process, and while it can arise in various conditions, it does not reflect the physiological changes that characterize inflammation.
