I know this is an older thread, but I have to agree with other posters. Perimenopause is a major trigger. I never had frequent migraines, only once every year or two. Then once the “vasomotor” symptoms of peri started, it all changed. Clogged nose left side, tinnitus left side, achy neck/shoulders, facial pain left side- even the eye tearing. Very much like the autonomic symptoms of a cluster headache, but not following a schedule like clusters, and no intense pain. EVERYTHING is on the left side of my head! Just like Ellis. The dizziness is mostly an "off kilter? thing, feeling like on a boat. But once in awhile I get full spins for a few seconds. Neuro says cluster sub type of migraine. Something about allodynia.
Storms are a trigger for me now (not before), as are many processed foods/spices. I have decided to work with a hormone dr. to use progesterone bioidentical cream, since in the past it helped my anxiety/sleep. My estrogen is sky high, and progesterone almost nil. I am almost 47. My hormone dr. said my migraines will probably be gone in a few years, given my particular history. We hope, once the levels are stabilized with the cream, these attacks will lessen. For now, I use nasal spray, advil, Relpax, and will be trying Nortryptiline shortly.
