Tinnitus in young people that lasts for 24 hours can be caused by noise irritation, cerumen impaction, neurogenic tinnitus, trauma, and ear diseases. 1. Noise irritation: working in a noisy environment can cause constant tinnitus. 2. Cerumen impaction: The accumulation of cerumen in the ear forms a lump, blocking the ear canal and causing tinnitus. 3. Neurogenic tinnitus: without any external stimuli, but can feel the sound of cicadas, buzzing, etc., the specific pathogenesis is unknown. 4. Traumatic injury: the impact of external forces, resulting in head and neck nerves, muscles and other injuries, causing persistent tinnitus. 5. Ear diseases: for example, secretory otitis media, otitis externa, boils on the external auditory canal, etc. can lead to tinnitus, ear pain and other symptoms. It is recommended to consult a doctor in time to find out the cause of the disease and follow the doctor’s instructions, so as to avoid delaying the condition.
