Bad Odor in Nose And Another Strange Symptom

I know that this topic has been posted many times, but I seem to have a symptom that I haven't heard of before from others who have a bad smell in their nose. Whenever I am drinking something (it can be anything), I smell a bad odor (almost a fecal-like smell). Has anyone experienced this, and do you know why this smell would appear (I notice the smell when I breathe in through my nose while drinking, just to be more specific. I certainly hope it has something to do with either my nose or breath because I most definitely do not want this fecal smell to be emanating from my body (to be honest, I almost never go out in public anymore because of this smell for fear of others smelling it). Any advice would be appreciated.

I too have had these symptoms. Mine started with a tooth extraction. I've had two rounds of antibiotics and still have the problem. Any suggestions?
