I can certainly tie an increase in migraine frequency and severity to meningitis. I now know I had migraines all my life, but they were nowhere near as frequent or debilitating as they are now. In 2007, I, too, had viral meningitis. Recovery took some time, and I was not diagnosed with migraines until 2009. But I am convinced there was a connection between my meningitis and migraines.
Thanks for posting. I am anxious to hear of other migraineurs have had meningitis.
