Thank you for your questionCustomer
I'm sure that you understand how difficult it is to know exactly what is going on with you considering the limitations of this forum. For that reason, I cannot diagnose you with any condition. Rather, I can suggest a few possible problems that fit the description you have given and educate you on them. This is in no way a substitute for an evaluation by a health care professional.
First, I would try and find out if this smell is real or not. Perhaps you could invite someone to where you are experiencing this order and ask them if they smell anything? Don't tell them what you're smelling, you don't want to bias them.
If you establish that the smell is not real, then you could be suffering from phantosmia. (phantom smelling). Phantosmia can be a symptom of multiple problems.
The most common cause of phantosmia are upper respiratory infections, and sinus infections. Once these infections resolve, the bad smell should resolve as well. This doesn't explain the chest tingling very well, though.
I will list the other possibilities. They are too numerous to go into much detail.
I cannot explain the tingling in your chest other than perhaps you are getting very anxious worrying about this smell disorder. Being 47, you should have your risk calculated for having heart problems. If this is ok, I would try and see how you feel after you get this smelling problem taken care of.
Let me know if you need any clarification.
