For a couple of weeks now I have been experiencing a foul, organic, almost "burnt" taste in the back of my throat. I would describe it as the sort of aftertaste eating a steak might produce. I do not have bad breath, and the taste is only occasionally present, doesn't last long, and is not particularly intense. I do not get heartburn, nor do I have any strange digestion things going on. I am not pregnant. I am concerned that because others cannot detect a foul smell and because it has been going on for so long despite a varied diet, that something systemic could be going on. However, having no other symptoms I can think of off the top of my head, I can't rationalize seeing my primary care physician. Any idea what's up? Thanks.
