Hi.
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain white/yellow pustules at the back of throat along with over tongue and roof of mouth and pain seems to be probably due to a severe case of bacterial
throat infection known as
Strep Throat..
White pustules are pus pockets that further confirms towards bacterial infection..
It does not seems to be due to sexually transmitted infection as it happened two days after
unprotected oral sex as mostly the sexually transmitted infection takes a week or so to occur due to
incubation period that is symptom free period in between the exposure to infection and occurrence of symptoms..
For confirmation consult an Otolaryngologist or an ENT expert and get evaluated..
He can do investigations like Throat swab culture can help in diagnosis..
You can be advised:
-Antibiotics like
Augmentin OR
Azithromycin to resolve the infection..
-Anti-inflammatory painkillers like
Ibuprofen can be taken to relive pain. -----Doing warm saline gargles, steam inhalation and using a humidifier in your room can be very much relieving.
-You can also suck throat lozenges to soothe the throat..
-Gargle with numbing mouthwash containing Lignocaine..
-Gargle with antiseptic solution like few drops of betadine in water..
-Chew Vitamin C pellets to boost up the immunity..
-Avoid spicy and chilled foods..
Hope this information helps..
Thanks and regards.
