Thanks for posting your query.
You are most likely suffering from chronic persistent tonsillitis
along with GERD
Persistent acid reflux
may also cause persistent irritation in throat with overlying bacterial infection.
Presence of pus pockets is a recurrent source of throat infection
You should again consult with ENT surgeon for throat infection and should go for throat swab culture & sensitivity for detection of exact microorganism and effective antibiotics.
You should also consult with internal medicine specialist/ gastroenterologist and should take neksium along with prokinetics.
