Hi, My name is Sandy I have had migraines since I was a child I am now 45 and for the last 6 years I have had a very sensitive sense of smell.Loads of smells set a migraine off.  and I can even smell peoples b o now which is not very nice. I had been smelling gas and like a sewerage smell in our street for 2 years but no one else coiuld smell it. It is not very nice. I do feel for you. The only thing suggested to me was to carry something with a smell that you like which does not set your migraine off and sniff it . It sort of counteracts the other smell. I use the cold cream muscle relaxant. Its menthal and it has levementhal in it. It helps me. Good luck in finding your own personal smell. I hope it helps.
