Incense and migraines?

Does anyone who suffers from migraines notice how much they intensify if you're around burning incense? Or is this all in my head? I'm already receiving treatment for migraines and obviously have to get my medicine changed but the only times the medicine doesn't work is when I'm around any burning incense.

Edit:

Thanks for the replies, i tried google and it wasn't helpful at all, so knowing scent can be a trigger makes me feel a bit better since i know what to avoid now.
