Hi.
Welcome to HEALTHCARE MAGIC.
I have gone through your query and can understand your concerns..
As per your complain swollen tonsils or
Tonsillitis after
Oral sex might be due to improper maintenance of Genital hygiene leading to infection in throat and tonsils leading to inflammation and pain..
It is not due to less sleep but it is due to infection..
I would suggest you to consult an Otolaryngologist and get evaluated and he can advise you investigations like Throat swab culture to rule out for bacterial or Viral infection and can advise you to take antibiotics like
Augmentin, Anti-inflammatory painkiller like
Ibuprofen, do warm saline gargles, steam inhalation and suck throat lozenges..
Avoid spicy and chilled foods..
Drink plenty of warm water..
Hope this information helps..
Thanks and regards.
