Look at his paper by Irene. S Gabashvili, PH.D on Systemic Malodor and PATM. I totally disagree with PATM described as a Malodor problem, otherwise it should be called “Stinky Syndrome of me” instead of Allergic. Every person I’ve met either scratch their nose, sniff, cough, sneeze, have headaches and running noses, say I smell fine 100% all the time, but say I do irritate them, nose, sinus, eyes, throat, and give them headaches and nauseous feelings. It’s like I’m spraying them with a chemical that combines chili-pepper, headaches and flu, all in one, but 100% odorless. Either way read it and make your own conclusion.
