Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain cold like symptoms but not having cold exactly can be due to
Sinus infection or Sinusitis as at times the symptoms of
post nasal drip, congestion, nasal drainage and cough due to irritation of throat with post nasal drip and all these can be symptoms of Sinusitis..
I would suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations like PNS VIEW x ray or MRI scan of sinuses can help in diagnosis and treatment can be done accordingly..
In case if Sinusitis is diagnosed you can be advised to take antibiotics like Levofloxacin, anti inflammatory painkiller like Ibuprofen,decongestant like
Phenylephrine or Pseudoephadrine, mucolytics like Ambroxol, anti allergics like Benadryl, cough suppressant like
Dextromethorphan and along with it steam inhalation, saline
nasal irrigation and decongestant nasal spray can be advised..
Avoid chilled foods and air conditioning atmosphere..
Hope this information helps..
Thanks and regards.
