your smelling of diesel sounds like a phantom odor that really does not exist in the environment. there is a disorder called phantosmia. it presents itself in the form of an olfactory (smell sense) type of hallucination. it can be caused by nerve damage to the brain's olfactory system certain toxins and medications emotional stress trauma and viruses. it is also a condition sometimes seen in epilepsy. resolution is directed at treating the root cause.
occasionally i have a 'condition' where i smell something similar to what diesel smells like every time i breathe. . when i inhale all i smell is what smells like diesel. this lasts for anywhere from three days to two weeks and it stops as suddenly as it starts. i have not noticed anything that specifically 'triggers' it. just wondering if anyone else has ever experienced this and what may be causing it and if i can do something to avoid or stop it. i have type 2 diabetes high blood pressure and severe asthma and not sure if any or all of these contribute to this.
