Sinus Infection causing Odout

[raul79]

I have noticed that everytime i get a cold or sick, my sinuses naturally worsen but it causes a very bad odour from my frontal sinus cavity and upper head near my forhead.  The odour has been there since i got a raelly bad sinus infection 3 years ago. I was given some nasal spray but the sinus infection never went away and the smell never went away...it was not a strong odour, but i could notice it by the end of the day. I went to the doctor for the smell and i used a fungus shampoo for 3 months but nothing happened.  I have recently caught a cold again and the odour is strong again.
I notice that the mucus coming out when i blow my nose is green/brown, with some blood and it carries the same smell that is present on my head.
And suggestions on what to do? Why the odour? Should i be making a 10th doctors appointment again?

What you report, including the malodorous green/brown drainage, suggests a chronic infection of one or more of your sinuses.  This could be caused by bacteria or a fungus or it could be an allergic non-infectious response to a fungus.  You should have a careful, complete exam of your nose and throat, by an ENT specialist, and a CT scan of your sinuses, along with a culture of your nose and the suspect sinus.  The specimen should be sent for a smear and cultured for both bacteria and fungi.  If a needle aspiration is done, it should also be sent for anerobic bacterial culture.
