Re: Rotten egg smell. Long term concussion?
Just as a person can have a visual hallucination or an auditory hallucination, you can also have an olfactory hallucination in which you truly believe as if you have smelt something that no one else is aware of. Roses, smoke, cigars...the eoisodes are usually not long lasting. Following a concusion it could be due to some residual swelling or what is known in young children as 'shaken baby syndrome'. The surface of the interior of the skull is not smooth like the exterior, it is jagged. During a concusion, and during your recent injury, the brain is jarred inside the skull and hits these inside jagged ridges. Are you noticing the rotten egg smell as a never ending experience, or did it come and then pass? I wouldn't be concerned unless hte episode was not ending, in which case I would then consult the doctor.
