Dehydration
People become dehydrated if they don't drink enough water or their body loses too much fluid. The first signs are thirst, trouble concentrating, a headache and dizziness. It then helps to quickly drink enough. Severe dehydration is a medical emergency.
Middle ear infection
Acute middle ear infections are one of the most common illnesses in infants. Many parents then face sleepless nights with a child that cries, has an earache and fever, and can’t sleep. The earache generally goes away on its own within two to three days, and serious complications are rare.
