Aura
It had been an ordinary day at Baker Street. Mrs. Hudson was downstairs making lunch for them, although she constantly protested that she wasn't their housekeeper. Sherlock deduced that she was treating them as if they were the children she had never been able to have. Her protests not unlike American mothers claiming not to be their children's maids.
John was sitting on his chair reading that day's newspaper. A rather tedious activity in Sherlock's mind, but it gave his friend something to do. As a result, the doctor was not in the kitchen hassling him about his latest experiment. He was trying to see if there was a way to detect if one's beverage had been tampered with. Then he noticed it.
It was a small dark spot in the center of his vision. Like someone had taken a picture and the flash had caused a temporary blindness. He blinked a couple of times and scoffed when it didn't go away immediately.
"What is it? Something turn blue when it was supposed to turn pink?" There was a rustling of paper. "Hang on! Is that my mug you're using?"
"Yours was the cleanest one. I'll wash it when I'm done. You don't really mind, do you?" He scowled as he pinched the bridge of his nose.
"Headache?" John walked in and regarded him.
"No, but I do appreciate the concern. Must have looked into the light." It was the oddest thing, though. Normally flash blindness faded. The little blind spot he had seemed to be getting bigger. He looked at the cup on the table and the handle was completely covered. He closed his eyes in thought.
"Are you seeing spots?"
Sherlock groaned. The last thing he needed was John in doctor mode. Still, it was best to be honost. "Spot. Singular. Seems to be spreading. I do hope I'm not going blind. I'd have to learn to rely on my other senses and that would be tedious."
John hummed. "Well ... you've been on a case, which means you haven't eaten or slept well. Has this ever happened before?"
Sherlock sat back. "Not to my knowledge." He glared at the table.
John sighed and patted Sherlock's shoulder. "I'm sure it will pass. When it does, if my theory is correct, then I strongly suggest you go lie down in a dark and quiet room."
Sherlock turned as John walked away. "Why? What do you think it is?"
"Sounds, to me, like a migraine aura. One of the blokes in my unit used to get them and made the poor sod miserable when fighting started up." He shrugged. "Considering the strain you put yourself through, it's a wonder you never got one before."
"Migraine? I'll have to analyze it." He started clearing off the table.
John sat down and chuckled. "Good luck with that. Depending on the person, they can range from mildly annoying to wanting to knock yourself out just to get away from the pain. Thought might be impossible afterwards."
Sherlock nodded. "Right, then. I'll try and remember it so I can record my findings later." By the time he'd finished tidying up the kitchen table, the blind spot had gotten larger and moved to his peripheral vision. It was like something was passing him slowly on the left.
John watched him go. "Don't hesitate to text if you need something."
Sherlock snorted. "I'm sure I can handle a little headache, John. I'm only going to lie down, as you suggested, to appease you."
It wasn't until the dizziness and nausea hit him that he understood that a migraine was more than just a little headache.
Author's Note: Just a little one-shot drabble. I suffer from migraines, and it is a PAIN in the backside when I get an aura at work. Keara has had to work with me, more than once, while I was wearing sunglasses because I couldn't take the flourescent lights. Good thing we work in the back where no customers can see us.
