Study Notes
Classifying Pain
- Pain can be classified by cause (e.g., cancer, cardiac), pathophysiology (e.g., nociceptive, neuropathic), or duration (acute vs chronic).
- Acute pain lasts less than six months; chronic pain persists beyond six months.
- Treatment varies by type and individual response to pain.
Nociceptive Pain
- Most common pain type, arising from stimulation of nociceptors due to trauma, inflammation, or tissue damage.
- Sensations can be sharp, burning, aching, cramping, or stabbing; can originate from visceral or somatic locations.
Types of Nociceptive Pain
- Visceral Pain: Originates from internal organs, typically dull and cramping, lasts longer (e.g., pancreatitis, cancer).
- Somatic Pain: Emanates from skin, muscles, or bones, sharp and localized, often short-lived (e.g., burns, fractures).
- Referred Pain: Felt in one location, though it originates from another (e.g., heart attack pain in the jaw).
- Radiating Pain: Extends from the source to adjacent areas (e.g., gastroesophageal reflux).
Other Pain Types
- Neuropathic Pain: Arises from nerve injury; persists post-stimuli; sensations include numbness and burning; associated with conditions like diabetes and cancer.
- Psychogenic Pain: Pain perceived without a physical cause, linked to emotional or behavioral factors (e.g., headaches, back pain).
- Acute Pain: Rapid onset, short duration; subsides with healing (e.g., injury, labor).
- Chronic Pain: Enduring pain lasting over six months; may be continuous or episodic; linked to conditions like fibromyalgia and arthritis.
Acute vs Chronic Pain
- Acute pain lasts less than six months and is self-limiting.
- Chronic pain exceeds six months and can be considered a disease condition, often resistant to treatment.
Nociceptive Pain Characteristics
- Nociceptive pain arises specifically from trauma, inflammation, or tissue damage.
- Distinction from referred, chronic, and phantom pain is essential for accurate diagnosis and treatment.
