Hi JJ. I also am hypersensitive to smells and have been for as long as I can remember. Often, I get headaches or migraines b/c of perfume, smoke (even the smell of smoked cold-cuts!), vinyl, new leather, rubber, glue, and so many other things. I’ve also felt my lips and tongue start to tingle and a few times my throat has felt swollen during my strange ‘neurological episodes’ but this almost always happens when my blood pressure is extremely low. Maybe our hypersensitivity to scents is related to mast cell activation?
