If you've noticed a reduction or change in your hearing, schedule an appointment with a healthcare professional so they can examine your ears for any obvious abnormalities and ask you pertinent questions about your history and lifestyle. Most problems that negatively affect hearing are benign and reversible, so don't be scared to seek professional opinions.  Don't try to self-diagnose or get an unqualified friend or family member to dig in your ears. Your healthcare professional may refer you to an ear specialist for further examination. An ear specialist (otolaryngologist) or audiologist can conduct a more thorough ear exam, including a hearing or audiometric test, which evaluates the ability of sound to reach the brain. This is a relatively quick and painless test and vital to understanding if your hearing issue is permanent or not. The otolaryngologist will be able to tell you if your problem is related to SNHL or CHL. Make sure you get the doctor to explain the diagnosis clearly and provide you with various treatment options. If your problem is SNHL, then treatment will likely be forthcoming from an otolaryngologist. However, if you problem is CHL, then you have many more treatment options, possibly including some simple and safe home remedies depending on the cause. Researching hearing loss on the internet will give you an idea of potential treatments, especially for CHL, but always stick to reputable medical sites.
