Study Notes

Concept of Pain

Pain is an unpleasant sensation and emotional experience, often a result of tissue damage.
Nociceptors (pain receptors) transmit pain messages to the brain through specialized nerve cells.
Pain signals are processed in the thalamus and relayed to various brain areas, which can modulate pain severity.

Types of Pain

Acute Pain
- Sudden onset, typically sharp, lasting from minutes to six months.
- Common causes: surgery, broken bones, dental work, burns, or cuts.
Chronic Pain
- Ongoing pain lasting longer than six months, persists post-injury.
- Linked to conditions like headaches, arthritis, cancer, and back pain.
Neuropathic Pain
- Caused by nerve damage, described as shooting, stabbing, or burning sensations.
- Often sensitive to touch and can hinder daily activities.
Nociceptive Pain
- Results from tissue damage, characterized by sharp, achy, or throbbing feelings.
- Commonly experienced in joints, muscles, and skin.
Radicular Pain
- Occurs from compressed or inflamed spinal nerves, radiating down the legs.
- Symptoms include tingling, numbness, and muscle weakness, often associated with sciatic pain.
Nociplastic Pain
- Arises from altered nociception without evident tissue damage.
- Common conditions include fibromyalgia and chronic pelvic pain, often requires tailored care.

Pain Theories

Neuromatrix Model (Ronald Melzack)
- Pain is produced by the central nervous system, involving four components: body-self neuromatrix, cyclic processing, sentinel neural hub, and activation of the neuromatrix.
Pattern Theory of Pain
- Pain is generated by non-specified receptors; sensation depends on the spatio-temporal pattern of nerve impulses.

Pain Management

Non-Pharmacological Interventions
- Hypnosis: Induces altered consciousness to reduce discomfort.
- Comfort Therapy: Includes companionship, heat/cold application, and exercise.
- Physical and Occupational Therapy: Encompasses aqua therapy and strengthening exercises.
- Psychosocial Therapy: Involves individual, family, and group counseling.
- Neurostimulation: Techniques like acupuncture and acupressure.
Pharmacological Interventions
- Step 1: Non-Opioid Medications: NSAIDs (e.g., aspirin, ibuprofen) reduce inflammation and pain.
- Step 2: Compound Analgesics: Combination of drugs (e.g., codeine with paracetamol) for mild to moderate pain.
- Step 3: Opioid Medications: Strongest painkillers derived from morphine, mimicking body's analgesic system (e.g., tramadol, buprenorphine).

Comparing Acute and Chronic Pain

Onset: Acute pain has sudden onset, while chronic pain develops gradually.
Cause: Acute pain is linked to specific tissue damage; chronic pain often results from long-term conditions.
Duration: Acute pain lasts fewer than six months; chronic pain persists beyond six months.
Severity: Acute pain correlates with tissue damage; chronic pain may not correlate with damage.
Characteristics: Acute pain is sharp and localized; chronic pain is dull and generalized.
Relief: Acute pain lessens with injury healing; chronic pain often persists despite healing.
