Tinnitus is a common condition characterized by the perception of sound in the absence of external auditory stimuli. It is often described as a ringing, buzzing, or humming in the ears, but can also manifest as other types of sounds. Tinnitus can have a variety of causes, including hearing loss, exposure to loud noise, certain medications, and head or neck injuries. It can also be a symptom of underlying conditions such as ear infections, cardiovascular disease, and Meniere’s disease. Symptoms of tinnitus can include a constant or intermittent ringing, buzzing, or other sound in the ears, difficulty concentrating or hearing due to the presence of the tinnitus noise, and difficulty sleeping due to the perceived noise. In severe cases, tinnitus can have a significant impact on daily activities and quality of life.
