Backed Pained

Cracking bones of spinal cord,
pills no effect and cannot afford,
unable to work with this much pain,
stability of mind and insanity of brain,
aches like electric shocks spike quick,
while the chemicals make more sick,
unable to move when need to do,
cannot explain from any point of view,
nodding with agreement hurts more,
holding back the tears that should pour,
late at night when it is worse,
what was done to deserve this curse.
