If you are experiencing a sore throat, difficulty swallowing, redness in the throat, and small white spots on the tonsils, it is recommended to calculate your modified Centor score to determine if you should consult a doctor. You can refer to the document provided in the conversation for instructions on how to do this. If your score is 3 or higher, it is advised to seek medical attention. Otherwise, rest, drink plenty of water, and take Tylenol as needed. Symptoms should improve within 7 days.
