PAIN
Pain is a sensory experience that is highly subjective to the individual. Pain may be acute or chronic and is characterised in various ways, according to duration,
intensity, type (dull, burning or stabbing), source, or location in the body. Pain and discomfort in Parkinson’s usually arise from one of five causes: (1) a musculoskeletal problem related to poor posture, awkward mechanical function or physical wear and tear; (2) nerve or root pain, often related to back or neck arthritis; (3) dystonia and the sustained twisting or posturing of a muscle group or body part; (4) extreme restlessness; and (5) a rare pain syndrome known as ‘primary’ or ‘central’ pain, arising from the brain.
