When the morphine wore off

[Bassim]

I am wondering if my sentence is grammatically correct.

When the morphine wore off, the unbearable pain shot through Peter's body, and he screamed, calling the nurse to help him.

When the morphine wore off, the unbearable pain again shot through Peter's body, and he screamed [STRIKE], calling[/STRIKE] to the nurse to help him.

or

When the morphine wore off, [STRIKE]the[/STRIKE] unbearable pain shot through Peter's body, and he screamed [STRIKE], calling[/STRIKE] to the nurse to help him.

teechar,

I understand that "pain" can be written with or without an article.
I am wondering if I write my sentences like this, would they be correct?

1. Bob felt terrible pain in his abdomen.
2. I was writhing with a pain which shook my whole body.
3. Peter was screaming with pain after a car drove over his foot.

Yes, those are fine.
