I have chronic migraine. Most days I have a low level of pain I may or may not forget about unless I stop and sit still, a light fuzzy feeling in my head that is just shy of buzzing or tingling, and general fatigue. Some days it ramps up to brain fog and dizziness, less forgettable pain and more significant fatigue with some queasiness. Occasionally, but not infrequently, I'll get a "proper" migraine with something of a prodrome (usually brain fog and nausea), something of an aura ( tingling right side of head or tinnitus), proper pain phase (sometimes including severe neck tension), and postdrome where I feel like a limp rag that been wrung out and rolled over with a steam roller. On the rare occasion that will be bad enough that I'm truly incapacitated.
Weather, allergies, stress... I think those are my primary triggers. I've tried the anti seizure meds, they did nothing; the beta blockers bottomed out my blood pressure so aren't an option; the antidepressants help the depression but not the m migraines; and I can never remember what the fourth type is, but it didn't help either. Cgrps helped for about a month, but instead of helping even more over the next two, they steadily helped less. I built up a tolerance to migranal in three doses over the course of four months. Imitrex works for about three or four months if I only take three or four a month, but then I have to take two or three off and I never know when to take it anyway since you're supposed to take it at first sign and I live in a constant state of first sign. Take it too early and you waste a dose. Take it too late and you waste a dose. For a very specific type of presentation, Excedrin's formula works two or three times times a month.
So I pretty much just live with it. Take Excedrin when I can, but often forget to even do that.
