very possible. Or that if you had it long enough you've had systemic damage that flares up.There are some fringe theories that sometimes it can be for life. We have a friend who occasionally has flare-ups which usually result in a migraine for 2-3 weeks straight. There's not a lot of data to support this idea, but she used to have migraines 9+ months out of the year and once a doc identified it as Lyme, she very rarely has them.
