His neck ached with the effort of not looking back.

He walked until his neck ached from gazing up at them.

My arms and neck ached from keeping the binoculars raised.

His neck ached from being in one position too long.

Her neck was aching - because she'd slept on it funny, right?

His neck ached from staring up at the tall man.

The night was dark about him; his neck ached from holding the position for so long.

The boy's neck ached, so he turned back the other way.

His neck ached from where he had been leaning back.

His neck ached after sleeping on the sofa all night.
