>>84429502Most of the times migraines are bad and will stop you from working especially if you're seeing auras in lights, etc. For a day, at most, maybe 2, as long as you take the steps for recovery (hydrate, adequate sleep, etc). But she's been having migraines persistently for a while now.
The cut off for if it's normal is usually 3 days persistant, and it's been far longer than that, so she needs to figure out the underlying cause and get treatment and or medicine. It might be related to her prescription being out of date, as eyestrain can also lead to migraines. Hoping it works out and she gets the help she needs.
