You simply don’t expect it.
It happens so quickly:
A button pressed, bone on nerve,
Then shock, pain, quite suddenly,
Like voltage through wires,
Fan out from shoulder, sickly,
Through neck, along arm to hand,
With a pervading, venomous verve.
Then the limb throbs and aches,
Every single movement takes
The breath, in agony, away:
The body’s equilibrium astray…
And it happens so quickly,
You simply don’t expect it…
It really does cause severe discomfort...
