Hi welcome to healthcare magic, I am sorry that you are well
It sounds like a rhinosinusitis (because the nasal mucosa in normally involved and sinusitis normally occurs with rhinitis
are air filled spaces that are located in the forehead, eyes, cheeks and nasal bones.Sinusitis can be allergic, viral, bacterial or fungal in origin.Some of the symptoms include facial pain
, nasal discharge, blocked nose, persistant coughing,postnasal drip (this may contribute to the smell). The fact that the symptoms have been ongoing for a month may suggest a bacterial infection which require the use of antibiotics.Additional medication that is somethings used of sinusitis include nasal sprays, decongestants and antihistamines.
You should consider visiting your doctor for an assessment. Your doctor wil take the history and conduct an ear,nose and throat examination. He or she will treat as necessary.
There are other causes of bad odor from the mouth (halitosis
) so if it doses not resolve with treatment of the infection then you may want to consider visiting a dentist
I hope that this information is helpful
