Hi..
Drainage down the throat also known as
Post nasal drip can occur due to causes like Sinusitis, Upper Respiratory Track infection,
acid reflux, allergies etc..
In your case it seems to be due to SInusitis or
sinus inflammation..
I would suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations depending on clinical symptoms like PNS View x ray, nasal endoscopy, upper G.I Endoscopy etc can help in diagnosis and treatment can be planned accordingly..
In case of infection you can be advised to take a course of antibiotics, ant-inflammatory painkiller, decongestants oral as well as
nasal spray, anti allergics and mucolytics..
As of now you can take anti allergics like Levocetrizine, Mucolytics like Ambroxol..
If it is due to acid reflux antacids and
proton pump inhibitors like Omeprazole and diet modifications can be advised..
In case of allergies anti allergy medicines and preventing exposure to allergen can be advised..
Do warm saline gargles and steam inhalations..
Limit exposure to dust and also avoid chilled foods..
Sip on warm water..
Hope I have answered your query. Let me know if I can assist you further.
