These parts of the body are actually the upper end of the airways system and are prone to viral infections, particularly in the colder months. If you think you may have an infection but are wondering “What are the symptoms of (for example) laryngitis?” or have been told your child has glue ear but think “What exactly is glue ear?” then this section will provide you with some answers. There is also information about hearing and balance and common conditions affecting them such as ear wax, hearing loss in older people and vertigo. You can read all about the symptoms and check the available treatments in our doctor-authored leaflets.
