His chest was beginning to spasm with the need to breathe.

James watched her leave, and his whole chest began to ache.

That was all he could make out before his chest began to tighten up from lack of air.

The woman's chest began to rise and fall more rapidly, but she held her ground.

As if he sensed when her awareness changed, his chest began to rise and fall.

Carter's chest began to hurt as he passed the wagon.

Her chest was beginning to tighten with a familiar pain.
