my sense of smell has been progressively going for awhile but now I have no sense of smell or taste at all. And for the past few months there's a constant sickly sweet smell everytime i breathe in. its nothing to do with my house etc as its everywhere i go, even outside and its getting so bad its literally making me feel sick its so sweet. does anyone have any idea what this could be??? i had sinus infections on and off for the last few years, could it be to do with that? Thanks
