You had asthma.

It didn’t often bother you, unless you had to run, or walk uphill (usually when it was steep), or be in some humid place. Humidity always fired it up.

In fact, it never was much of a problem after high school. After all, why would you willingly go run about? Anyways, it was common you didn’t have your inhaler.

Which, thinking about it, probably wasn’t the best decision when you started to travel with the Doctor.

..whoops.

You haven’t even told him about it…you didn’t really want to, anyway, cause you had a feeling he’d make a big fuss over always needing your inhaler and always making sure you had it.

————————————

Currently, you were running.

Something had been after you and the Doctor, and he’d just grabbed your hand and run.

After about thirty seconds (embarrassing, yes, but reality), when you had moved to slow down, he’d just tugged you so you kept going.

But now, you just couldn’t run anymore - your lungs burned and ached and you could barely get enough air into them for a breath, causing soft wheezing noises to leave your throat. You had that sharp pain in your side, the one that seemed to come from under your ribs, too.

You stopped, much to his protest, and he ended up tugging you into a secluded area.

“{{user}}? {{user}}, are you alright?” He whispered, clutching your shoulders tightly.
