'''Growing pains''' are recurring [[pain]] symptoms that are relatively common in children ages 3 to 14-16. The pains normally appear at night and can affect the calf or thigh muscles of one or both legs. The pain usually stops on its own before morning.

Growing pains are one of the most common causes of recurring pain in children.  Although these pains reliably stop when the child has completely finished growing, it likely has nothing to do with growth.

== Signs and symptoms ==
Growing pains usually affect both legs, especially the calf muscle in the lower leg or the muscles in the front of the thighs. Pain may also occur in the ankle muscles and tops of the feet.<ref name="Lehman 2017">{{Cite journal|last1=Lehman|first1=Patrick J.|last2=Carl|first2=Rebecca L.|date=March–April 2017|title=Growing Pains|journal=Sports Health|volume=9|issue=2|pages=132–138|doi=10.1177/1941738117692533|issn=1941-0921|pmc=5349398|pmid=28177851}}</ref><ref name="Mohanta 2014">{{Cite journal|last=Mohanta|first=M.

The pain is frequently, but not always, felt on both sides, simultaneously. Typically, the pains are [[Muscle pain|felt in the muscles]], rather than in the joints. The amount of pain can vary from mild to quite severe.

The pains most often begin in the evening or at night.<ref name="Lehman 2017" /> When the pains appear while the child is sleeping, they often wake the child up at night.<ref name="Mohanta 2014" />  The pains can last from 30 minutes to 2 hours or more, and are usually, but not always, gone by morning.<ref name="Mohanta 2014" />  Typically, the pains appear once or twice each week, but can occur more or less frequently.<ref name="Mohanta 2014" />

The pains are not in the same place as an injury, including [[overuse injuries]] such as [[shin splints]], and the child does not [[limp]] while walking.<ref name="Lehman 2017" />

==Cause==
The causes of growing pains are unknown. They are not associated with [[growth spurts]], and some authors suggest alternative terms as providing a more accurate description, such as recurrent limb pain in childhood, paroxysmal nocturnal pains, or benign idiopathic paroxysmal nocturnal limb pains of childhood.<ref name="Mohanta 2014" /><ref name="Goodyear_2006" />

Theories of causation include:
* [[poor posture]] or other mechanical or anatomical defects, such as [[Hypermobility (joints)|joint hypermobility]];<ref name="Mohanta 2014" /><ref name="Goodyear_2006" />
* [[Vascular disease|vascular]] [[Perfusion|perfusion disorder]],<ref name="Goodyear_2006" /> 
* lower [[pain threshold]] or a [[pain amplification syndrome]],<ref name="Mohanta 2014" />
* [[tiredness]],<ref name="Goodyear_2006" /> perhaps especially among children with weaker bones than average who have overexerted themselves;<ref name="Mohanta 2014" /> and 
* psychological factors, such as stress within the family.<ref name="Mohanta 2014" /><ref name="Goodyear_2006" /> 
Some parents are able to associate episodes of pain with physical exercise or mood changes in the child.<ref name="Uziel_2007" />

== Diagnosis ==
This diagnosis is normally made by considering the information presented by the child and family members, and by doing a physical exam to make sure that the child seems to be otherwise healthy.<ref name="Mohanta 2014" />  When the child has the typical symptoms and appears to be healthy, then laboratory investigations to exclude other diagnoses is not warranted.<ref name="Mohanta 2014" /><ref name="Uziel_2007">{{cite journal|year=2007|title=Growing pains in children|journal=Pediatric Rheumatology Online Journal|volume=5|pages=5|doi=10.1186/1546-0096-5-5|pmc=1869025|pmid=17550631|vauthors=Uziel Y, Hashkes PJ |doi-access=free }}</ref><ref name="Goodyear_2006">{{cite journal |vauthors=Goodyear-Smith F, Arroll B |title=Growing pains: Parents and children need reassuring about this self limiting condition of unknown cause |journal=BMJ |volume=333 |issue=7566 |pages=456–7 |year=2006 |pmid=16946319 |doi=10.1136/bmj.38950.463877.80 |pmc=1557982}}</ref>

When a child has growing pains, there are no objective clinical signs of inflammation, such as [[swollen joint]]s.  Children with growing pains do not have signs of any [[systemic disease]]s (such as [[fever]] or [[skin rashes]]), any [[Allodynia|abnormal pain sensations]], tender spots, or [[joint disorders]].<ref name="Lehman 2017" />  Children do not have growing pains if the pain worsens over time, persists during the daytime, only involves one limb, or is located in a joint.<ref name="Mohanta 2014" />  It should be excluded if the child is limping, loses the ability to walk, or has physical signs that suggest other medical conditions.

Childhood-onset [[restless legs syndrome]] is sometimes misdiagnosed as growing pains.<ref name="Mohanta 2014" /><ref name="Goodyear_2006" /> Other possible causes of pain in the limbs include injuries, infections, benign tumors such as [[osteoid osteoma]], malignant tumors such as [[osteosarcoma]], and problems that affect the shape and function of the legs, such as [[genu valgum]] (knock-knees).<ref name="Mohanta 2014" />

==Treatment==
Parents and children can be substantially reassured by explaining the benign and self-limiting nature of the pains.<ref name="Lehman 2017" /><ref name="Goodyear_2006" /> Local massage, hot baths, hot water bottles or heating pads, topical [[Liniment|heat rubs]] and analgesic drugs such as [[paracetamol]] (acetaminophen) are often used during pain episodes.<ref name="Lehman 2017" /><ref name="Uziel_2007" />  Twice-daily stretching of the [[Quadriceps femoris muscle|quadriceps]], [[hamstring]]s, and [[gastrosoleus]] muscles can make the leg pains resolve more quickly when it appears.<ref name="Mohanta 2014" />

==Prognosis==
Growing pains are not associated with other serious disease and usually resolves by late childhood.<ref name="Mohanta 2014" />  Commonly, episodes of growing pains become less severe and less frequent over time, and many children outgrow them after one or two years.<ref name="Mohanta 2014" />

Frequent episodes are capable of having a substantial effect on the life of the child.<ref name="Uziel_2007" />

==Epidemiology==
Growing pains likely affect about 10 to 20% of children, and the rate may be as high as about 40% among children aged four to six.<ref name="Mohanta 2014" />  Individuals can vary markedly in when they experience growing pains.

==History==
Growing pains were first described as such in 1823 by a French doctor, Marcel Duchamp, and the cause was attributed to the growth process.<ref name="Mohanta 2014" /><ref>{{cite journal|last=Evans|first=Angela M|date=28 July 2008|title=Growing pains: contemporary knowledge and recommended practice|journal=Journal of Foot and Ankle Research|volume=1|issue=4|pages=4|doi=10.1186/1757-1146-1-4|pmc=2553776|pmid=18822152 |doi-access=free }}</ref>  A century later, mainstream medicine thought that the pains were caused by a mild case of [[rheumatic fever]].<ref name="Mohanta 2014" />
