The thought hit him like a shot in the solar plexus.

It was a nice solid hit to the solar plexus.

The answer hit me like a blow to the solar plexus.

She put a hand on his solar plexus and pushed herself into a sitting position.

But the second came too quickly after the first, and struck him in the solar plexus.

The words hit me like a punch in the solar plexus.

Every time he saw her, it was like being hit in the solar plexus by a fist.

She saw an opening in the middle of his solar plexus.

I tell you, the thing made me feel as if my solar plexus had gone wrong.
