Thanks for writing to H.C.M. for your query.
I have gone through your query regarding tonsillar infection and not getting effect of antibiotic penicillin and analgesic Ibuprofen
. As you said that you already had staph infection twice in past.
Considering your symptoms it appears as you may be having staph infection this time also, so it will be better to o Culture and sensitivity of throat swab to identify the organism and to select proper antibiotic.
If after conservative treatment your tonsillar size remains bigger and you feel recurrent sore throat
than to decide for tonsillectomy
will be wise step.
