Ive smelled cigarette smoke (usually mutliple episodes each day) for nearly 4 months when there is no smoke, and no one else smells it. Often it seems hard to take in a deep breath when I have the symptom. Occasionally I have a mild headache or eye irritation too, but usually its only the smelling sensation.
HiT hanks for using Chat Doctor I think, you have dyslexia. It is a disorder described as any qualitative alteration or distortion of the perception of smell. Clinically, it is associated with a neurological disorder. Other causes may be upper respiratory tract infection, head trauma, sinus problem, brain dysfunction. Better to consult a physician or neurologist for proper diagnosis and management. Thanks
