Relationships between pain and schizophrenia
GD Watson, PC Chandarana and H Merskey
In an examination of the phenomenology of pain in 78 patients with
schizophrenia, 29 had current pain complaints. Of these 13 had an
appropriate physical cause, leaving 16 with pain of seemingly psychological
origin. The head, leg and back were the commonest sites. Complaints were
most often described in sensory terms. Pain plausibly related to a specific
delusion or hallucinatory process occurred only once, and no gross examples
of insensitivity to noxious stimuli or to self-mutilation were seen.
Patients with schizophrenia may have less pain than those with anxiety or
depression but certainly do experience pain both from physical and
psychological causes. The influence of phenothiazines on pain experience is
uncertain.
