A numbness and tingling in the arm caused by a pinched nerve in the lower back area.
The condition occurs when one of the major nerves to the arm is squeezed or compressed as it travels through your buttocks and above your lower back.
I can’t use my arms anymore because my armpal tunnel is starting up again.
Fred: Hey, why is your arm shaking so bad?
Karen: My armpal tunnel is starting up again.
Fred: damn, that sucks.
