HA come on quite bad, the past 3 days I've been a bit unwell, body aches, headache, sneezing, slightly blocked nose, not been too fussed about it until tonight, was having dinner and everyone was saying how nice it smelt and I couldn't smell it, now I am home I have tried to smell all different things and I can't smell anything, not even a strong aftershave, of course I am now thinking brain tumour as when I move my right eye especially upwards it feels like a slight pain/discomfort. Is it normal to lose smell like this?
