Tumblr Anon: Okay okay okay no ibs. Fair. What if Peter had cyclic vomiting syndrome that had pretty much stopped once he got the spider bite, then one night while on patrol he got kicked in the stomach or something or he lost coordination and swung into something hard - which was painful - so he's over at Tony's feeling these cramps and attributes them to the injury and says nothing until he can't stop throwing up and his guts are killing. Cue irondad to the rescue during his short flare up.

Hi again :) Sorry I couldn't do the last request! This one fits the bill perfectly, though! Threw in a little surprise for you as well ;)

WARNING:

DESCRIPTIONS OF VOMIT AND DIARRHOEA

Idiot. If there was one word to describe himself right now, he would choose idiot.

He'd been patrolling and was heading back towards the compound when he got distracted and swung a little too low, causing him to slam into the side of a building.

At a painfully high velocity.

His stomach had been cramping violently from the injury, feeling unforgettably similar to the beginning of a cvs episode. It hadn't affected him since the bite, so he pushed it away and continued his travels.

After reaching the tall building and slipping in through his window he removed his suit in favour of some comfortable tracksuit pants and an oversized T-shirt. Nausea had added itself to the mix of discomforts and was making his insides bubble ferociously. He thought a glass of water could help and made his way to the en suite.

Once there, however, the chemical smell that invaded his senses immediately dispelled any desire to consume said drink. He gagged lightly and stepped out of the room. However, the damage was done and he raced back to the toilet as he dry heaved into his hand. His stomach chose that moment to clench and push itself up his throat, vomit being forced into the toilet. The pain in his gut caused him to retch a few more times before returning to it's cramp-riddled state. He took a deep breath and relaxed.

The relief was short-lived. His belly gurgled and groaned, feeling like the bottom of it fell out, and he hurriedly switched position to sit on the toilet instead. He instantly felt mush fall out of him and into the water. It didn't last long, but it was enough for him to confirm the state he was in.

Not often did his cvs cause diarrhea, usually only if he'd gotten beat up and hit in the stomach. The belly-flop into the wall could easily have had the same effect. At least it was over with now. He'd learned that it only happens once, the rest of the time spent puking.

Speaking of, when he stood up and flushed the nausea came back full force and he doubled over to spill a mouthful of acid into the recently-clean water.

"The boss is aware of your presence, Mr Parker. Do you require assistance?" F.R.I.D.A.Y. spoke up. He'd forgotten the A.I. existed until now, remembering that she alerts Tony of his arrival after giving him time to change and settle down.

"Um, I-I think I'll be okay. Thanks." Is all he manages before vomiting again. He would much rather be on his aunt's couch with a bucket than a cold, tiled room, but he's embarrassed to ask for help.

"If you're sure, sir." The robotic voice sounds oddly uncertain, if it's not just his imagination warping it.

"U-um, actually… Can you ask Mr Stark to meet me in the lounge?" He's hesitant, but he needs to be more open about things that negatively impact his life, he supposes.

"Yes, Mr Parker."

He waits until he can stand without gagging and moves out of his room into the lounge. He steals the bin from his room on the way through.

"Kid? You're usually bouncing around my lab by no- Oh." Tony takes note of the boy's pallor and the receptacle he's carrying.

"Uh, I think it's a cvs thingy, Mr Stark. Sorry, I thought it was gone but I hit a wall and- uh-" The kid gags and a splatter echoes from the plastic he's holding. He'd checked Peter's medical history and seen the cvs listed, but when he asked the response was that it was gone now due to the bite. Obviously, he was wrong.

"Okay, then. Let's get you sitting down, first." He starts, being cut off by another splash. He guides Underoos to the couch and rubs his back until the vomiting stops.

"Sorry, Mr Stark, I didn't know-" Tony interrupts his apology.

"It's fine, Kid. It's okay. Just focus on feeling better."
