I have chronic migraines (20-24/month). For the last week or so I have this terrible odor that I smell that nobody else seems to smell. It's like sewer gas. I looked it up and that appears to be linked to migraines. I am wondering if anyone else has this phantom smell w/in the migraine sufferers. I almost don't want to breath in anymore! If anyone has a solution for this I would love to hear it or am I the only person that has experienced this?
