user-1: Is pain comprised of the four great elements. I believe it is because  it has hardness/softness, coolness/hotness, etc.

user111: No! Patavi, Apo, Tejo, Vayo are elements of Rupa. Pain is a sensation caused by those elements coming into contact with the sense doors while the the mind is present.

user295: The 4 elements can only be sensed through the scene doors, hence in the stand point of a mediator the 4 elements are sensations too. Without a living observer there cannot be any scene of the elements, hence consciousness, faculty, contact, sensation are essential and any experience of the elements is always through sensations or the characteristics of the elements which are felt.
As a side note, in case this question was motivated by trying to reconcile Pa Auk and U Ba Khin methods. This is one of the potential perceived differences between the Goenka/U Ba Khin meditation method and Pa Auk 4 elements meditation methods but at essence they are the same through 4 elements based method is slightly more granularity by further sub dividing the sensation based experiences based on the characteristics of the elements.

user8157: This question makes no sense. The four elements are material & not related to pain.
Pain is vedana kdhanda rather than rupa khandha.

Venerable sir, might there be another way in which a bhikkhu can be called skilled in the elements?”
There might be, Ānanda. There are, Ānanda, these six elements: the earth element, the water element, the fire element, the air element,
  the space element, and the consciousness element. When he knows and
  sees these six elements, a bhikkhu can be called skilled in the
  elements.
But, venerable sir, might there be another way in which a bhikkhu can be called skilled in the elements?”
There might be, Ānanda. There are, Ānanda, these six elements: the pleasure element, the pain element, the joy element, the grief
  element, the equanimity element, and the ignorance element. When he
  knows and sees these six elements, a bhikkhu can be called skilled in
  the elements.
