Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern.
As per your complain and presentation of symptoms it seems that you are suffering from
Peritonsillar Abscess secondary to bacterial infection causing Tonsillitis or
Strep Throat..
The pussy sac will gradually reduce in size after taking antibiotics..
Along with antibiotics you can take anti-inflammatory painkiller Ibuprofen.
Do warm saline gargles.
The white /yellowish coating on tongue can be due to
fungal infection known as Thrush and taking antibiotics is a common factor causing thrush because antibiotics kills good bacterial present in mouth that is responsible for preventing infections.
This is a reason that you are unable to find improvement as you are still taking antibiotics..
Nothing to worry, consult your physician again and get evaluated and he can advise you to take
oral antifungal medicines and nystatin gargles.
Sucking
Clotrimazole lozenges will help..
Take more of probiotics like Yoghurt and garlic..
Hope this information helps..
Thanks and regards.
