Rainbow's Doctor Visit

>"NOOOOOOOOOOOOOOO! Don't let that thing near me!"
"C'mon Dash, this isn't that bad. Everyone has had theirs so far, now it's your turn."
>You were currently in the Ponyville hospital, and it was time for tetanus booster shots. The other five had taken theirs like champs, but Rainbow Dash...
>Well, she wasn't being the most graceful about it, to say the least.
>"What if she slips? She might puncture an artery!"
"She's not going to slip." You deadpan, clamping your hands down on her wings to prevent her escape.
>You gave the feathery appendages a light massage to calm her, which wasn't working.
>"But what if?!"
>You sighed heavily.
"Would you feel better if I was there with you?"
>The pegasus stopped her thrashing about to think about it. You can hear the gears turning.
>"...no, I don't think so."
"Too bad, we're going in."
>With that, you lifted the struggling pony and slung her over your shoulder, carrying her into the office.
>You set her down on the cushioned recliner-esque chair, then immediately slammed the door shut before Rainbow could attempt to escape.
>There, you both waited. You were calm, Rainbow Dash was panicking and hyperventilating.
"Dash."
>"WHAT?!"
"Breathe."
>"I AM!"
>Her breathing was ragged, and silent tears were streaming down her face.
>"I don't want it, I don't want it..." She mumbled between labored breaths.
>Wow, that was kinda heartbreaking.
>Still, it was one now, or thirty later. At least, that's what your parents had always told you.
"You'll be fine, Rainbow. I promise."
>The clicking of the door was the only warning you got to hold Rainbow down again.
>The door slowly opened, revealing Nurse Redheart with a case in her mouth.
>You weren't entirely sure that was sanitary.
>Redheart sat the case down, then turned to the two of you with an amused expression.
>"Well now, Rainbow Dash. Someone I never expected to see in here, especially uninjured."
>Dash didn't respond, instead intensely glaring at the nurse.
"Well, it was quite the feat doing that." You replied, keeping the pegasus still.
>"I can imagine." She chuckled, before prepping the syringe.
>She slowly filled it with a clear fluid, and Dash's eyes locked to it.
>Her pupils dilated, and the hyperventilating started again.
>You stood between her line of sight and Redheart.
"Dash."
>"WHAT!?" She shouted, fear taking over.
"You need to breathe. With me, okay?"
>You took a slow breath in.
"In..."
>You slowly exhaled.
"Out."
>You inhaled again, and Rainbow copied you.
>She let her breath out early, but was still visibly calmer.
>You moved aside, and Rainbow affixed a heated glare to the nurse.
>Redheart, for her part, blatantly ignored said gaze. Probably no stranger to it.
"Dash, look at me. It'll hurt more if you watch it."
>Rainbow ignored you, still intently watching the needle.
>You took a direct approach, this time grabbing Dash around the muzzle and forcing her to look at you.
>"Mmmmph?!"
"Look at me."
>Redheart crept closer, and you took a deep breath, recalling a song you had heard on the radio a few minutes before you landed in Equestria.
"Every-thing's, gonna be alright~
Rock-a-bye, Rock-a-bye~"
>Your singing voice wasn't the best, but it was enough.
>"Anon..."
"Mm?"
>"...that was terrible. Who taught you how to sing, the back of a cereal box?"
>Redheart had already administered the treatment, and the prismatic-maned mare hadn't noticed.
"There, was that so bad?"
>"What?"
>Dash looked over, and Redheart was gone along with her syringe kit.
>You swore that nurse was some kind of ninja in a past life.
"All done, Dash."
>"R-really?" She sniffled, before wrapping her hooves around your neck.
>"You're the best..." She muttered into your chest.
>Today was a "Dash owes you one" kinda day.
