9Changes in Tastes
In some serious cases when your sore tongue is caused by an infection or medical condition, your taste function might be impaired. This means that you would lose a part of your ability to taste, depending on the severity. Many people might have this symptom temporarily or for a longer time if left untreated. The main cause might come from your central nervous system, which would be damaged due to the underlying cause of your sore tongue. [9]
