Hi welcome to the health care magic According to history provided it seems to be pharyngitis associated with acid reflux... Your posterior pharynx examination has to be done by nearby doctor for seeing congestion in posterior pharynx or tonsillar enlargement Investigation done with CBC as preliminary work up You can be prescribed antibiotic course for five days Salt water gargles in hot water done three times a day Semidolid meal taken more as compared to solid meal Pantoprazole tablet prescribed for acid reflux for two week Head elevated while sleeping If no improvement and difficulty in swallowing continues then barium x ray and endoscopy like investigation needed to be done by gastroenterologist Take care Hope your concern solved
