Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concern..
As per your complain it seems that you have an upper
respiratory tract infection that is superseded with bacterial infection and green phlegm along with
metallic taste in mouth is due to it..
Other causes can be
lung infection..
I would suggest you to consult an Otolarynglogist and get evaluated and he can also advise you
sputum culture, throat swab culture and chest x ray to rule out for the exact cause of the symptoms and treatment can e planned accordingly..
He can advise you antibiotics like Augmentin or Cephelexin, decongestants like
Phenylephrine, mucolytics like Ambroxol, anti allergics like Allegra, warm saline gargles, steam inhalations and use a humidifier in your room..
Avoid spicy and chilled foods..
Sip on plenty of warm water..
Hope this information helps..
Thanks and regards.
