I have been suffering from severe sinus problems. I used to have headaches on my right side. I had a septoplasty done. The headaches are gone now. However, I still think the sinus secretions are thick. This seems to give me a really bad breath. I've tried nasal sprays and even mucinex.. They help.. But, the breath problem is still noticable.
My doc says that my sinus is wide open since the septoplasty and has no answers for the bad breath. I have a feeling that he thinks that i'm imagining it.. I'm not and I cannot wait for the problem to just go away.. And yes, the sinus secretions seem to get thicker when i'm inside an airconditioned building..Outside, it's not fully gone, but it is definitely better...
The continued thick, mucus secretions could continue to get trapped into the sinuses causing secondary infection and thereby consequent to the same cause bad breath. Homeopathic medicine has good remedies like sticta, kali bichromicum etc. To get rid of the secretions, infection and the cause of bad breath.
