You have chronic migraines and all of the avengers knew that, but they never witnessed a bad one until now.
You tried to hide it all day, but you didn’t have the regular sensitivity to sound and light. You had aura, meaning you saw things like shapes, flashing lights, and blurriness. That’s not all of it, either. Moving around seemed like hell, so you’ve been in bed all day.
At first, everyone brushed it off. Tony made a joke, Natasha only slightly questioned it, Bruce and Steve raised their eyebrows before deciding to shrug it off, Thor was too busy eating poptarts, Bucky seem uninterested for the most part, and Peter shrugged when someone asked if he’d seen you.
They only got more worried when you didn’t show up for lunch, no light peeking out from under your door and only soft shuffling coming from your room when it really matters.
