About growing pains
Although they can be distressing, growing pains are fairly common and don't cause long-term harm.
Despite the name, there's no clear evidence to suggest that growing pains are the result of growth spurts.
This is why some doctors prefer to use the term "recurrent nocturnal limb pain in children".
Symptoms of growing pains
Below are symptoms related to growing pains.
- are felt as intense, cramp-like pain in both legs
- most often affect the calves, shins or ankles, but can also affect the thighs
- develop in the evening or at night (often after more active days), but shouldn't be present in the morning
Your child's ability to walk shouldn't be affected by growing pains and there should be no signs of limp, physical injury or infection.
If your child's symptoms are different to those described above it's unlikely they have growing pains. For example, if only one leg is affected or they're limping. In these cases, take your child to see a GP (see section below), as they may have an underlying medical condition.
Causes of growing pains
The cause of growing pains is unknown.
Although they seem to be more common in active children and children with loose, flexible joints (joint hypermobility). They also tend to run in families.
What to do
Growing pains can usually be treated at home.
Sometimes, giving them painkillers before bedtime after an active day can prevent them waking in the night.
Children under 16 should not be given aspirin.
You can also try firmly massaging your child's leg muscles and joints or applying warmth to their legs, for example with heat packs.
Supportive footwear such as trainers might help prevent growing pains. Make sure any shoelaces are tied and that shoes with Velcro are fastened firmly.
When to see your GP
You should see your GP if your child's symptoms are particularly severe or suggest they may have another condition, such as:
- pain in just one leg
- pain also affecting the arms or back
- pain that occurs every night or continues during the day
- swollen joints
- a high temperature (fever)
- loss of appetite
- weight loss
- reluctance to walk, or a limp with no obvious cause
They may refer your child to hospital for further assessment.
Link with restless legs syndrome
Some doctors are investigating whether there's a link between growing pains and restless legs syndrome (RLS). RLS is a condition of the nervous system that causes:
- an overwhelming urge to move the legs
- an unpleasant sensation in the legs that eases once the legs are moved
It's not currently known whether growing pains are an early form of RLS, or an entirely separate condition.
