My 7 year old has for a couple of days been saying he can smell smoke - there is no smoke anywhere (I have a really sensitive sense of smell myself). I'm really worried as I'm sure in adults smelling things that aren't there can be a sign of serious things. Am waiting for a GP callback but has anyone else's child had this? It seems to be common in adults but not children. He hasn't stuck anything up his nose and he hasn't got a cold or had a cold recently. Seems fine otherwise.
