Understanding the mechanisms involved in the degeneration of pain receptors or nerve fibers in HSAN II can also help in developing novel treatment options for patients suffering from intractable pain.
Relaxation can promote natural endorphins that would block pain receptors and reduce the amount of pain that is experienced.
Visceral pain receptors are found in the muscles and linings (mucosa) of hollow organs.

There is a distinct possibility that, during certain times in some children's growth phases, the tension across the epiphyseal plate may be released in a manner similar to a microscopic "earthquake", placing increasing tension on the periosteum, thereby triggering the firing of the pain receptors that reside in this tissue.
