Sam

He's crying and your not.

Of course no injury has been really bad except for one where you fell down the stairs and somehow bruised the bone.

He wouldn't let you go up or down stairs for a month.

Bumblebaby

He's a cinnamon bun when you're sick or hurt. Always asking if you need something or want cuddles.

But you would not believe how badly he panics. You got sick with the flu and couldn't talk, kiss him, or keep anything down. He thought you were dying.

Red and blue

He's not too concerned unless it's really serious, like getting hit or throwing up, serious. You once got food poisoning and he wouldn't let you do anything for weeks on end.

Ratchet

Ratchet loves you so much and doesn't want to ever see you hurt so he learned human doctor stuff for you. You also get hurt a lot so it was a necessity for him to learn how to give stiches, create a cast, ect.

Megatron

He seems like he doesn't care, but he really does. He just won't show it unless A. You two are alone or B. It's something drastic.

Soundwave

Forget ever telling him you are sick or hurt. He will hunt down anyone who caused you to get hurt or sick, all while mothering you.
