text: what is wrong with my nose? this is going to sound crazy but it's true.  it started yesterday at my daughter's dance recital.  i started smelling roast beer with onions and garlic.  i thought it was someone with bad breath.  then today i'm in my living and the smell comes back again.  no one else in my family can smell anything.  i hate roast beef.  i went to the internet but couldn't find anything.  has anyone ever smelled something that didn't exisit?  also, i am taking a medication and i don't know if that could cause this problem. it could be a mental thing - you only think you're smelling it. sounds like something stress-induced. you need some rest and relxation.
