Strange smell

[Lynn S]

This question pertains to my father who rarely visits the Dr.
He is 82 yrs old and he has congestive heart failure.
As of late, he says he experience a strange smell in the middle of the night, actually from 11pm to 400am. He says it smells like a "deadly gas smell" (for lack of a better description).
There are no strange smells in the house or the immediate area outside. Nor can anyone else smell this odor.
Could this be a medical condition ?

Does your Dad have any mental problems? These smells might be delutional , smells that aren,t there are like voices that aren,t there, and sence they are at night, when the elderly tend to be more cofused. I would take him to see a neurolgist, smells could also mean something in the brain. any way he could be evaluated.

I have heard people smell burning hair smell when a stroke is coming on.

I also think the problem might be neurological... I don't know if it's a stroke or anything else, but a few neurodegenerative diseases, like Alzheimer's, start by probs concerning the smelling sense. Considering his age, I would say it might be helpful to take him to a neurologist... if he refuses, just have one stop by the house... I think docs can do that for someone his age... no point in tiring him.

Good luck! :)

I have been experiencing an unpleasant odor and it only happens when i am on the subway or in the bus. I do not get it anywhere else. I have been to a doctor and she is out of ideas. I have tried every known home remedy and nothing. It is strange since I only get it on public transportation. It is really stressing me out.

Can anyone please help me?
