  1. Pain Management Review and Cases Curtis M. Grenoble, MS, PA-C Lock Haven University PA Program PA Days, Summer 2009

  2. The most important part… • The HISTORY!! • Be sure to obtain the full list of symptom attributes for pain • LORCATES • This will help you to identify the pathophysiology and choose proper management • Be aware of malingerers and drug seekers • Inconsistent history that doesn’t match findings on physical exam

  3. Types of pain… • Nociceptive (tissue) pain • Due to tissue damage • Two subcategories • Somatic • Musculoskeletal pain (muscle, joints, bones, ligaments, skin) • Characteristics: often sharp, well localized, reproducible • Visceral • Originates in organs (thoracic, abdominal, and pelvic cavities) • Characteristics: often poorly localized, vague, deep ache/cramp, may produce referred pain • Commonly treated with • Anti-inflammatories • opioids

  4. Types of pain… • Neuropathic (Nerve) Pain • Damage or dysfunction of nerves in the peripheral or central nervous system • Traumatic injury, burns, nerve degeneration (MS), pressure, inflammation, infection (shingles) • Characteristics: burning, electrical sensation, may describe as a shock…but may not describe as pain but rather “going to sleep” • Referred pain to area innervated by the nerve • Light touch of affected area may elicit severe pain • Anti-inflammatories & opiods usually ineffective • Tx: anticonvulsants (gabapentin), TCAs (amitriptyline), sodium channel blockers

  5. Types of pain… • Sympathetic Pain • Complex Regional Pain Syndrome I • Reflex Sympathetic Dystrophy • Chronic pain with a pattern suggesting overactivity of the sympathetic nervous system often with a history of injury but may not be able to identify • Complex Regional Pain Syndrome II • Causalgia • Caused by serious injury to major nerve trunk that is immediately obvious • Both respond best to combination treatments including anti-inflammatory/pain and nerve pain
