Classifications of Pain:
acute: sudden onset with a typical duration of less than 6 months, usually associated with injury
chronic: constant pain that persists more than 6 months, usually associate with a particular injury, cause or illness
cancer pain: often due to the compression of peripheral nerves or meninges. May also be due to cellular and tissue damage following surgery, chemotherapy, radiation or tumor growth.
note: Pain is classified by mode of origin and transmission
Nociceptive pain: is due to the stimulation of nerve fibers that transmit signals
in a normal way from nerve endings to brain centers.
Somatic pain: pain originating from muscle, soft tissue or bone. It is usually
well localized and described as deep, aching, or boring. It may be worse with
movement. Some examples are bone metastases, osteoarthritis, and
Visceral pain: pain originating from internal organs or viscera surrounding
them. It is usually less well localized and can be referred. Often described as
deep aching, cramping, or squeezing. Some examples are bowel obstruction,
brain tumour, and appendicitis.
Neuropathic pain: is the abnormal sustained stimulation of the nerve fibers that
transmit signals from the nerve ending to brain center and/or from a dysfunction
in the central nervous system.
dysesthetic pain: described as burning, electrical sensations or pins and needles and/or lancinating pain, described as stabbing, shooting, or hot poker
examples of neuropathic pain:
Emotional pain: the essence of this pain is the feeling of brokenness or shattered self. When perceived this pain is often avoided or hidden beneath self protective strategies. Unlike physical pain, that can be alleviated with pain medications, emotional pain must be first approached (acknowledged, validated) by the individual. Secondly, it must be reprocessed and assimilated into the individuals cognitive structures and view of self. This process allows for emotional awareness, a means to address the emotional arousal and finally regulation of the emotional pain itself.
