But it isn't in fibromyalgia (where people
experience widespread pain without a known cause), food craving and overeating, Parkinson's disease, and speech problems after a stroke.
These findings reflect those of a study conducted in Finland among schoolchildren, which found that children with
widespread pain reported more emotional and behavioural problems than those without
pain, and showed that tiredness during the day was a risk factor for the persistence of
pain.18 Furthermore, a recent study of children aged 3 — 17 years attending a medical practice in Australia found that children
experiencing frequent abdominal
pain were more likely to be anxious and
experience sleep disturbances when compared to children with no abdominal
pain.19
