Peter Parker's leg was damaged beyond repair during the fall of the warehouse. Trapped under tons of rubble, his leg was crushed between the concrete ground and a steel girder. It took every ounce of his energy to lift that building off himself, and the fight after drained the rest. He swung away to hide on top of the boardwalk ride, but of course Tony found him. In good time too, he was losing blood and starting to fall unconscious.

———or a story in which Peters leg was amputated and he can still feel the pain——————————————

Phantom pains:
Phantom pain is a perception that an individual experiences relating to a limb or an organ that is not physically part of the body.

"Friday, locate the kid I know he's here" tony told his AI.

"Yes boss, he appears to be on top of the roller coaster to your left. I would hurry he is losing blood rapidly and has major nerve damage to the right leg"

"Shit, ok thanks fri" he shot off to where he saw the red and blue suit. Peter was right at the top, slowly slipping down until he was almost horizontal. "Hey kiddo, lets get you fixed up huh?"

"Mr'ark" the boy mumbled.

"Yeah it's me, god kid I told you to leave it. But I am going to say thank you"

"Of c'rse" Peter coughed, his leg shifting with the movement. He let out a whine of pain and tears sparkled at the corners of his eyes.

"Ok no more chit chat let's go" tony bent down and lifted the kid gently into his arms, trying not to move his leg too much. He flew off towards the compound and made it there in record time. He ran straight to medbay and told Friday to get Bruce and cho.

"Hey tones what's up, Friday said you needed me?" Bruce asked as he entered the lab. Tony had placed peter on a bed and deactivated his suit.

"The kid I told you about, he was hurt pretty bad"

"Ok I can take a look but I hope you called cho"

"Oh I did" tony sighed watching Bruce attach peter to the electronic vital signs monitor.

"He has the rapid healing right? So most of his injuries should be fine, but I'm going to take him for scans you can wait here"

"Ok" he watched Bruce wheel the bed towards the compounds radiology department.

"Ok kid, lets see what's wrong" Bruce muttered, he had been wanting to meet this kid for so long, but not like this. Tony hadn't stopped talking about how smart he was since he first met him and Bruce couldn't wait to let him help with gamma ray studies.

He waited for the scans to pop up and looked over them. "Ok Friday record data" Bruce cleared his throat and began observations, "Slight fractures to three ribs, one clean break, fracture in ulna and radius on left wrist, as well as a left anterior shoulder dislocation.  That's just the torso, Tony said leg? Oh yes, left leg has slight meniscus tear, oh god that was not the leg he was talking about. How did we not see this, oh right his suit is red anyway. Umm, so complete shattering of femur, I've never seen it this bad, Friday what are your thoughts, chances of keeping the leg?"

"Unfortunately Dr banner, I have run a set of scans on the tendons as well as bones and it appears the leg will not heal, even with Mr.Parkers advanced healing. If the leg is left infection risk is high and could kill him completely. My best recommendation is full amputation of the leg."

"Oh, poor kid he's so young too." Said Cho from behind Bruce.

"Hey, thanks for coming. These are his scans, I'm and I'm guessing you heard Friday's prognosis?"

"Yes, and I have to agree. The rest of the injuries, besides the dislocation which can be healed through setting it, can heal on their own. The leg however, it needs to go. The sooner the better too, I have a team on standby, we just need to transfer him to our surgical unit."

"Ok let's go, I'll set him up for transfer" Cho nodded and headed towards the OR wing. Bruce wheeled peter out after and beckoned tony over.

"So what happened, how bad is it" tony asked, stumbling over this words, he's really worried

"Tones, I'm sorry he's going to be fine, but he needs a full amputation"

"Oh god, why did I let him do this"

———time skip three months——————————————
Things had been going well, Peter had met the whole team (civil war didn't happen for plot reasons). Once Steve had met peter he called Bucky up and made him come to the Tower. He wanted Peter to meet someone who he could relate to.

Other than that, Peter had gotten a prosthetic leg which he had gotten pretty good at using, and soon he was back to training with the team. It wasn't until he was in the middle of training with Clint when he realized something was off. When Clint kicked his prosthetic leg he felt it. You're probably being crazy it's not there. Until he kicked it again causing peter to fall, yeah I felt that. He excused himself and went to the bathroom.

"Think Parker, you can't let them know. You can hide it, pretend it's the pain from where the prosthetic meets the hip"

He went back out and resumed fighting.

———————————————————————————————
Things had been going smoothly, no one questioned why he would wince when kicked and that's exactly what he wanted. He just never expected the pain to be so much worse when he wasn't fighting. When his body wasn't jacked up on adrenaline the pain set in. He could feel the pain of his bones crushing and tendons tearing. It usually happened at night when he was alone because he took his leg off to sleep. He could hide it then, but not in the living room during movie night.

The way they were all sitting made it uncomfortable to keep the leg on, so with Tony's urging he took it off. Forgetting what happens when he does. Twenty minutes went by and the pain started.

He sucked in a breath and squeezed his eyes shut. He prayed no one noticed, but it wouldn't work because Tony was right next to him, and he felt Peters shark breath and the way he started shaking.

"You ok kiddo?" He whispered.

"Mhm" Peter mumbled, in too much pain to talk.

"No you're not, what's wrong"

"Nothing I'm, fi-ouch" he yelped. Grabbing the blanket over where his leg would be. When he felt nothing he looked at his hands.

"Peter?" Bruce asked eyeing his hands. "Are you ok"

"Mhm" he said again, shaking more.

"Oh, Peter are you in pain?" Bucky asked getting off the floor to take Rhodes place on the couch.

"Y-yeah"

"But how his legs gone?" Tony asked, genuinely curious.

"It's called phantom pains, I used to get them all the time now not so much. Peter when we were training you winced when someone hit your prosthetic. Is the pain like that, like you could feel the kick?"

"No" he breathed out.

"So it's the pain of remembering? You can still feel the way it felt when it first happened, it never healed so that's the last memory you have of your leg"

"Yeah, that makes sense, ouch" he cried, tears making their way down his face.

"Have you felt this before?"

"Yeah, whenever I take it off" he sniffles.

"Oh" tony whispered, "peter you take it off to sleep right? So every night?"

"Yeah" he gasped grabbing nothing again.

"Oh I'm so sorry bambino I should have known"

"No, tony don't blame yourself you wouldn't have know unless you've been through it" Bucky said. "I'm going to try something that works for some people, it might work for you. It's called mirror box therapy, I need a body mirror"

"I've got one in my room" Steve said standing up. He returned quickly withy he mirror.

"Thanks, ok peter put your leg out straight, lean your back on tony." Buck stood up and kneeled down next to Peter, positioning his leg so it was across the whole couch. He took the mirror and leaned it on pillows so it reflected the leg that was there. From Peters point of view it looked like he had two legs. "If it starts to hurt look at the mirror, remember that your leg is not being crushed, it does not hurt. It should help you ground yourself and stop the pain"

"Thanks Bucky, it kind of feels better"

"Of course kid, glad I could help. If it even starts hurting at night and you can't get the mirror yourself you can have Friday call me, Tony or anyone I'm sure you all know what to do now right?" Everyone nodded. "Good, now lets finish this movie"
