My wheelchair has become an electric chair.
Wires crisscross my body,
charged with a low current,
slowly extend and expand,
like waves surging,
from the feet upwards
to the calves, the thighs,
and finally the buttocks.
Suddenly,
my toes are hit
with a short, sharp electric shock.
My legs jerk violently outward,
then tap on the footplates
at regular executions.

Pains are normally experienced, and not easy to be expressed in words. However, your vivid descriptions strike my heart with such a shocking wave that I have started to understand the feelings those EOL patients at our palliative care unit must have.
Thank you for sharing them, K.K., and I admire your courage very much.
May you be comforted.
Dear Chian Li, I am pleased that my descriptions help you to understand pain and feel for those EOL patients at your palliative care unit. I hope they find comfort, relief and peace. KK
