Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain
sore throat along with white dots in throat and pain during swallowing seems to be due the
throat infection only and the white dots seems to be pus pockets secondary to infection..
Sinus
drainage can be a cause for it as the sinus drainage leading to
post nasal drip that flows to the back of throat leading to infection and irritation in throat..
You should consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigation like throat swab culture can help in diagnosis and treatment can be done..
You can be advised to take a course of antibiotics like
Augmentin, anti-inflammatory painkiller like advil, do warm saline gargles 3 to 4 times a day, do steam inhalation and use a humdifier in your room..
You can also be advised mucolytics and decongestants..
Drink plenty of warm water..
Avoid spicy and chilled foods.
Hope this information helps..
Thanks and regards.
