Hi--I was recently diagnosed with a-fib. Not thrilled, it runs in the family, so here I am. BUT--I am wondering if anyone out there also has a-fib and migraines. If so, what do you notice about the two conditions, as in interaction? Do you find a migraine often precedes an a-fib event? I know headache can be a symptom of a-fib. Yesterday I woke up with a migraine, and had an episode of a-fib by noon. Do you find that your meds prescribed for a-fib (such as cardizem) make your headaches worse, since headache can be a side effect of that drug?
