Hi thanks for contacting HCM... Here if pus is present then pain is throbbing type severe..... You might have post nasal drip from sinusitis and rhinitis and feeling of such symptom can occur.... Your pharyngeal examination done in detail.... Along with it otoscopy done to rule out ear problem especially otitis infection...and look for tympanic membrane congestion .... Take amoxyclav antibiotic... Also use antiinflammatory drug like antihistaminic drug benadryl..... Steam inhalation useful... Soft and bland diet taken..... Lymph nodes in neck has to be palpated .. One tsp ginger juice with honey useful herbs... Keeping these in mind consult Ent surgeon for examination... Take care.... Dr.Parth
