Adam, I think I may have the same problem that you had with the fogginess, light headed, etc. I feel like it is connected to my eating.
But, based on your post, I had a CT Scan done. It turns out I have a significantly deviated septum, and cysts (not polyps) but still, some substance in my maxillaries. My doctors seem to have a hard time grasping that the aforementioned symptoms could cause the resulting effects.
Is there any way I could get the name of the doctor that handled your issue (operated, diagnosed, etc.)?
Any help would be immensely appreciated.
