Hi! How are you feeling now? Hope you followed the advice to have an appointment with your doctor. The infection might worsen if you don't have it treated the earliest time possible.
Tonsils that have white spot/s on them is a typically a good indicator that you have an active infection of some kind going on. They can appear with viruses as well as bacterial infections and occasionally with STD's. Are you able to bring up any colored phlegm/sputum when you cough? Do you have an elevated temperature? Do you have any burning/pain in your chest or in your upper back? Do you feel run down and tired? Have you tried gargling with warm salt water 4x per day since the appearance of the white spot on your tonsils? I would suggest making an appointment with your primary care provider and be sure to include the oral sex in the information, so that all appropriate cultures can be done on you! Good luck!
