Thank you for posting your query at DoctorSpring.com
You are suffering from recurrent chronic tonsillitis. Now you had two episodes and last one was follicular tonsillitis and on treatment with azithromycin you had drug rash which is improving now.
With next episode you should do one throat swab for pus culture and sensitivity. That will help in deciding correct antibiotic. Otherwise first line drug is amoxicillin. So next time you can start amoxicillin with clavulanic acid 625 mg twice daily for 5 days after discussion with your Ent specialist.
More then 5 episode of tonsillitis in a year is an indication for tonsillectomy surgery also. But it is an elective procedure , so we can wait and watch and can plan later also.
Hope this helps
