Clinical Classification of Pain
Pain can be divided into nociceptive and neuropathic types of pain, and can be a mixture of these two types.
It is of clinical importance to try and distinguish the types or components of a patient’s pain since this assessment has clinical management implications in the use of analgesics, adjuvant drugs and other analgesic modalities.
Caused by invasion and destruction of or pressure on superficial somatic structures like skin, deeper skeletal structures such as bone and muscle and visceral structures and organs.
- Types: superficial, deep, visceral
- Superficial and deep nociceptive pain is usually localized and non-radiating
- Visceral pain is more diffuse over the viscera involved
Caused by pressure on or destruction of peripheral, autonomic or central nervous system structures.
- Radiation of pain along dermatomal or peripheral nerve distributions
- Often described as burning and/or deep aching
- May be associated with dysesthesia, hypoesthesia, hyperesthesia and allodynia
- May also be accompanied by lightning-like jabs of brief sharp pain (lancinating pain)
