Smell

I have a strong chemical smell 24 hours a day that no one else can smell ?? its starting to drive me nuts.

Smelling odors that are not real is called several things, including phantosmia or olfactory hallucinations.  Sometimes simple things can do this, like recently having a respiratory infection, or having stopped up sinuses, or a migraine can do this.  But since it can also include things going on in the brain, for example problems from a head injury, or temporal lobe seizures, or stroke, you MUST visit a neurologist on this one, rather than going by what we say here.  

A couple other things are, if you recently changed laundry detergent, fabric softener, soap or shampoo, this can cause strange smells.  Also, if someone in your household recently used bug spray all over the place, it could even be that.  And then sometimes medications can cause strange smells.  But like I said, you will have to visit a doctor, because it could be a sign of something rather serious.
