Dear Liz, As Peculiar As Your Symptom Sounds, I Can Relate. I Too Have Gone Through This, For A Long Time I Smelled Odd Things And Had Tastes In My Mouth. I Hardly Get That Anymore, But Recently I Did Taste Metallic Like Pennies In My Mouth. I Had Bouts With Smelling Odors Or Thinking My Skin Smelled Odd, Dont Know If It Was Nasal Issues But I Have Had Soooo Many Symptoms Over The Last 2 Yrs. That I Chalked This Up To One More....has Ceased....the Metal Taste Is Horrid....hope This Was Helpful....pam
