I am type 2 insulin dependant diabetic, currently with BG over 250. I have the taste of metal in my mouth, also buzzing in the ears, dizziness , sudden movement of the head increases buzzing and dizziness and causes vision changes. i have electrical shock feelings, similiar to that as if you put your tounge on a 9 volt batttery, in my head. I have allergies as well, and have some thick mucus. I don t kow if i have a pinched nerve in my neck, a blood clot in my neck, a sinus infection ( no facial tenderness or sinus pressure) or if this is from elevated blood glucose. I have experienced this before, the metalic taste is new. some times the floor feels like it is moving up, spacial relationship is all wrong
the BLOOD SUGAR levels can cause all these problem sand sometimes the medicines(insulin)or the oral medicines cause allergies to increase and some symptoms are of diabetic neuropathy metallic taste can be due to more acid formation in the stomach which overflows in mouth sometimes or the post nasal Chat Doctor.
