Affecting up to 45 per cent of youngsters, growing pains tend to
hit between the ages of seven and 12. They are caused by the muscles
and not the bones. One hypothesis is that during a ‘growth spurt’,
a child bones grow rapidly. The muscles which surround these bones
struggle to keep up with the speed of the bone growth and therefore,
as they are stretched, become very tight. They pull on their
attachments via their tendons, which can be very painful, and can
sometimes result in conditions such as Osgood Schlatters. Growing
pains tend to make themselves known after a day of heavy exertion.
Although they are fairly common and can be painful and distressing, growing pains will not cause long-term damage.
