thanks for your query
History seems that you have sever tonsilopharyngitis
you were on treatment but no relief.
better to have throat swab for culture and sensitivity and treat accordingly.
Meanwhile take any broad spectrum antibiotics Like amoxiclav
or Azithromycine 500 once daily with antiinflammatory drugs like tab chymoral
plus and antihistaminics like tab levocet or fexofenadin,
and junk foods
Salt water or any antiseptic gargle 4-5 times a day is better.
Thanks a lot
