For the last couple of years, sometimes very frequently, sometimes a little less often, I smell something... weird. It's not really a bad smell, it's just that I've never smelled anything like it before, I can't even describe it. It doesn't matter where I am, or who I am with, I'm the only one that can ever smell it, and it is ALWAYS the same indescribably smell. I never thought much of it until now. I've also had a history with pretty bad headaches, but I don't really get them anymore- just once in awhile. And they were/are rarely actually migraines. I can't really speak for the last few years because I can't actually remember, but these last two times (today was the second in about a week), this smell triggers a dull, pounding headache. Should I see a doctor about this? Could this actually be something serious?
