Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain it seems that you are suffering from
Follicular Tonsillitis and the white sacs are pus pockets that are formed due to bacterial infection..
If you try to pop the sac it can get further infected and inflamed and can become painful..
I would suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations like throat swab culture can help in diagnosis..
In case if it is due to bacterial infection that seems most probable cause in your case you can be advised to take antibiotics like
Augmentin, anti-inflammatory painkiller like
Ibuprofen, do warm saline gargles and steam inhalations and use a humidifier in your room..
You can suck throat lozenges and sip warm water..
Avoid spicy and chilled foods..
Hope this information helps..
Thanks and regards.
