Talk to Ent Specialist on Chronic Tonsillitis And Pharyngitis

AoA doc, I have had this sore throat since July and during that time period i've seen several doctors. Three of them ran a full course of antibiotics for my tonsils (minute stones at the start but the inflammation would disappear and then reappear repetitively). My pharyngitis has been constant through out this time due to the post nasal drip (i had no previous history of sinus or any allergies). Most importantly, I haven't had fever or cough and the lymph node on my left side is swollen (benign nodules on it were seen in the CTscan). No home remedies work, gargles, painkillers and anti allergy barely do the job (as the doctors couldnt diagnose it, they showed doubt of a prolonged allergy). Besides this, i have had my blood tests done (HB levels were low but everything else was normal). Inflammation about a month or two ago dropped from 47-39. Can you share anything that might help or any tests which might help with further diagnosis .. it's been 4 months
