4. Hoarseness
Hoarseness or a raspy voice can be caused by many different things. The medical term for hoarseness is laryngitis. This occurs when the larynx becomes swollen and inflamed. The larynx is often referred to as the voice box. Most of the time laryngitis is caused by a common virus. In some cases it can simply be caused by overuse of the voice. In these cases the symptoms are not serious.
However, there are some causes of hoarseness, such as diphtheria that will require medical attention. If you are suffering from a sore throat, running a fever, and have developed laryngitis, it is important to seek medical attention right away as this could be a sign that you have been infected with the bacteria that causes diphtheria.
It can also be a symptom of several other significant medical issues such as throat or thyroid cancer, which is why it is important to determine the underlying cause.
