Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain
Tonsillitis can be due to bacterial or viral
throat infection and as you also have blocked nose and catarrh or phlegm production, it can be due to viral infection..
As viral infection resolves once the virus completes its cycle, therefore the treatment is mostly symptomatic to relieve the symptoms..
I would suggest you to take anti inflammatory painkillers like
Ibuprofen, decongestants like Pseudoephadrine, mucolytics like Ambroxol, do warm saline gargles, steam inhalations an use a humidifier in your room..
You can suck throat lozenges and chew a
vitamin C pellet..
Avoid spicy and chilled foods..
Drink plenty of warm water and take a
soft diet..
Hope this information helps..
Thanks and regards.
