How do you call a person who exaggerates pain to blame you?

Drama queen.

But is this about you two or is he like this about his general health? There is a difference, you know.

No actually when it comes to his general health he likes to brag how healthy he is.
Also if he hurts me accidentally he just laughs it off, turns it into a joke.
He is more focused on minor injury exaggeration and wants to blame it on me like I have caused it (even if I was not in the same room when it happened)

Or instead of saying something like "careful it hurts" he will immediately attack me and insult me: "are you stupid???! do you want to break my hand???!!!"

it's more than just "Drama queen" imho

Oh, so he's a touch verbally abusive.

Mama's boy?

Whiner?

Hyper sensitive?

all of them I guess. I was just wondering if there is some kind of medical term for this kind of behavior

This is just the beginning. He's showing you his character. It's crouched in these slight physical injuries that he blames on you, but will move to other life areas.

He will soon start blaming you for all his failures - financial, legal, family, school or job, health, etc.

Be warned.

Well, he could do. But other possible reasons can lead to such behaviour:
- he's bored
- he lacks excitement at home (this can differ from the above)
- his thinks his wife is uncoordinated, and thinks to make fun of such
- he's a child carrying on a stupid joke long past the time it stopped being funny
- some other similar motivation

People often underestimate the silliness that 'grown adults' can engage in.

A lot depends on the tone he uses, how he responds to her answers etc.

And because of that, it could be abusive (we aren't there to see). And if it is, it's also possible for such to lead to higher levels of abuse.

Could be narcissistic personality disorder

He sounds like a narcissist & a hypochondriac but it's really hard to say based on what you said alone.
