Hello and welcome to Health care magic, I am Dr Sriram Nathan and I shall try to help you with your problem Since you have already taken two course of penicillin and it has not resulted in a complete cure then it is either that the infection is resistant to penicillin or the diagnosis of tonsillitis is wrong. You may do these: -Take a course of stronger anti biotic like the amox-clav in consultation with your doctor. - More preferable take a throat swab for culture and sensitivity and then according to the report start the antibiotic. -You may also start a course of anti reflux medication like pantoprazole, along with an antihistamine like levcetrizine. Your doctor will know about these. -get a dental consultation and see if there is anything like a jagged teeth which is irritating the area -Take only non spicy, non oily and warm food and fluids -take proper meal at proper and correct time. Do not immediately lie down after food. -Take a course of multivitamin like zincovit in consultation with your doctor If you do not get better in a week or so then you must consult an ENT doctor who may advice further course of action which may include endoscopy and may be even CT to get a better picture take care and do not worry regards Dr Sriram Nathan
