Phantosmia: an olfactory hallucination makes you detect smells that aren't really present in your environment. It’s seen in people with Parkinsons disease, schizophrenia, Alzheimer’s and of course Lyme disease. It’s usually an unpleasant smell. For years as I went undiagnosed, along with multiple neuro and muscular skeletal symptoms, I would smell cigarette smoke when nobody was smoking. I detest cigarette smoking. Why couldn’t it be baked cookies? Because Lyme disease is a cruel bitch. Author Amy Tan, who’s recovered from Lyme disease, referred to her phantom smell as putrid rat. Yikes! Cigarette smoke doesn’t seem so bad compared to that. A few months into treating with IV antibiotics last fall, that symptom abated. Score ILADS doctor! Lyme disease you’re going DOWN!
