Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain continuous
post nasal drip seems to be due to causes like
Sinus infection or Sinusitis that seems to be most probable cause in
your case as you already have a history of the same while can also be due to upper
respiratory tract infection,allergies,
acid reflux etc..
I would suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations like PNS View or MRI scan of the sinuses, throat swab culture,
blood culture, complete blood picture etc can help in diagnosis and treatment and treatment can be done accordingly..
You can be advised to take a course of antibiotics, anti allergics like Levocetrizine, mucolytics like Ambroxol and also doing warm saline gargles and steam inhalations..
sip on warm water and avoid spicy and chilled foods..
Hope this information helps..
Thanks and regards.
