Over the last few months I will intermittently experience a strange blood-like taste in my mouth particularly when exhaling. There is no blood or anything like that so it's not literally bleeding, just a funny aftertaste that came on suddenly and now comes and goes. It's not coming from my mouth and does not seem to be coming from my sinuses and it's much more noticeable on the exhale. It's not changing the smell of my breath either just a funky flavor.
Does anyone else experience this and does anyone have any idea what this might be and what might be causing this???
