Wearing earplugs for a long time is especially likely to lead to the formation of otitis externa, with pain and redness in the external ear canal. Therefore, patients should wear ear plugs appropriately in their life, try not to wear ear plugs for a long time, and try to take them off when they sleep. If the patient has the above symptoms, it is best to go to the hospital for further examination and treatment to avoid delaying the patient’s condition.
