Writer's Block

Hand me a pen,
clutch in fist,
stroke like Nigella-
sweep and dust and mop and curl and dance,
sing for me Barcelona,
sing for me!
Oh my arm aches.
It buckles, it sags,
it warps in flagging nodules;
the pen is weighty.
Touch floor with my heel,
touch table with my wrist.
Pins and needles, numbness,
I can't feel my arm.
Left hand- not ambidextrous.
I'm stuck.
Stick in the mud,
Toad in the hole,
Camel through the needle's eye;
Writer's block.
