I've had this strange problem pretty consistently for the past year or so. My hands will have a strange orde. It smells very much like garlic. Though it comes and goes, it doesn't tend to completely go away, at least not for long, and it often gets very, very strong. So much so that I will notice it when my hand is still a foot away from my face. It's weird, and it's gross. I've tried going without garlic, onions, etc. in my diet, but it doesn't make a difference.
