Hi.. Can understand your concern.. As per your complain as your daughter had sore throat which was suspected to be due to bacterial (streptococcus) infection and she was medicated and got relieved of pain and discomfort but one thing that I would like to tell you that if she had cold and flu symptoms along with sore throat it could be more commonly due to viral infection.. The other part of the question is that as the infection must have got reduced the symptoms of pain has disappeared but it takes comparatively a bit longer time for the swelling to subside and will gradually reduce.. One thing that should be taken into notice that children have comparatively larger tonsils so you need to take care that whether the tonsils are really swollen or not.. I would suggest you to consult a Paediatrician and get a check up done so that he can rule out whether the tonsils are swollen or not and if swollen what is the reason behind it.. Few remedies can be done that can help in reducing swelling are.. Doing warm saline gargles 3 to 4 times a day.. Boil a pinch of turmeric with milk and give her bed time for 5 days as it has anti bacterial properties.. Avoid spicy and hard foods.. Drink plenty of water to maintain hydration.. In case if the tonsils are still enlarged and does not regress in size then there are chances that the enlargement is due to some unknown allergies and if she get repeated episodes of sore throat and difficulty in swallowing and pain then in case of chronic enlargements removal of tonsils or tonsillectomy can be advised..
