Sometimes it builds
To a degree intolerable
Some of it, it can be untraceable
The source unknown
Of the aching within
Impenetrable thoughts
Seeking a foundation

Strain comes out
In various ways
From your head to your toes
It will divulge

Aching in the head
Eyes flooded with blood
Tension of the mind
The body too
Tapping of the fingers
Shaking of the leg
It all soon, gives it away
