What is that sound?

Low humming in your head

The brain playing tricks

With noise no one else can hear

Or the crunch and crack of moving joints

Signalling age and ache

Gasps and moans not always suppressed

You choke them back so you don’t disturb others

Or the full cry of seized, spasming muscles

Mere movement eliciting shrieks

The sound of pain

From private and alone to loud and very clear

As never-ending fact of existence
