stop bleeding from injury

[GoodTaste]

Is "stop bleeding from injury" correct in English? Should it be "stop bleeding from an injury"?

===============

For healthy people, blood clots usually form to stop bleeding from injury.

Source: I am trying to explain the most common condition in which blood clots form.

"Use the version with "an injury".
I'd say,
"In healthy people, blood clots usually form to stop bleeding after an injury."
"Blood clots form to stop you from bleeding to death."
"In healthy people, blood clots usually form as a response to bleeding after an injury." This is less teleological.
"The most common condition in which blood clots form in healthy people is after an injury in which blood vessels have been torn leading to bleeding."

I wonder why simply "stop bleeding from injury" doesn't work.

Why should it always be "a wound" or "an injury" in this context?

It's a specific wound or injury.

"... stop bleeding from wound" is even worse. I'm wondering why you think a bare noun is appropriate here.
The following is also wrong: "My leg hurts from accident".

You can say:
"I'm still sore from surgery". I suppose you are thinking "injury" is similar.
In a sense, "injury" can be used that way. "If you need to remain at home from sickness or injury, please call the office." This is formal. You wouldn't say to a friend, "I was home from/with injury".
"His death was caused by accident or misadventure." OK. You can't use "wound" like "accident".

It's just the way we speak, and it's hard to explain.
