Ohhhh, Girl, I am so sorry!😥 Chronic sinusitis can be such a drag. I have similar issues. It seems like at some point, when none of the docs can help, we find ourselves grasping at straws. And sometimes/a lot, we keep drawing the shortest straw. As I was reading what you wrote, I immediately thought, "tonsils! Of course!" Then you said you'd had them removed already. Do you do saline nasal rinses on a regular basis? Like, daily? Sometimes that is effective. But if you've been to more than 1 ENT, I don't really know what to tell ya. Do you have a lot of nausea? This might seem random, but perhaps you should see a neurologist. If that kind of halitosis is persistent with ear involvement, it seems like neuro should get involved. Plus, I wonder if it is hormonal. Weird things happen when our hormones are whacked out. What about a dentist as well? They deal with more than just teeth as I'm sure you know. I don't know, I've had neurological involvement (among a bevy of other things) in my own life since infancy, and this just seems like a multi-disciplinary (several different specialists) issue.

My ENT actually recently discussed with me that hormones affect the sinuses greatly. I wonder if that is causing some of your sinus symptoms. I have migraines and chronic sinusitis and I only use nasal spray and OTC painkillers.
