Hello and Welcome to Ask A Doctor service. I have reviewed your query and here is my advice. As per your complain it seems that you have an inflammation in throat secondary to infection and it is leading to swollen tonsils causing tonsillitis. It can be either due to bacterial or viral throat infection. As you have started taking antibiotics Sefdin if it is due to bacterial infection. But if it is due to viral infection antibiotic will not work as they can cure only bacterial infection. I would suggest you to consult an Otolaryngologist and get evaluated and a throat swab culture can help in diagnosis and treatment can be done accordingly. As of now you should continue taking antibiotics for a week and also take anti inflammatory painkiller like Ibuprofen. You can gargle with warm saline solution. You can chew a vitamin C pellet daily. You can avoid spicy and hard foods and take a soft bland diet with plenty of fluids. Hope I have answered your query. Let me know if I can assist you further.
