Growing pains are recurring pain symptoms that are relatively common in children ages 3 to 14-16. The pains normally appear at night and affect the calf or thigh muscles of both legs. The pain 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.
Growing pains usually affect both legs, especially the calf muscle in the lower leg or the muscles in the front of the thighs. [1] [2] Less commonly, the arms are affected. They are normally felt on both sides. Typically, the pains are felt in the muscles, rather than in the joints. The amount of pain varies from mild to very severe.
The pains may start in the evening or at night. [1] Because the pains normally appear while the child is sleeping, they often wake the child up at night. [2] The pains often last for 30 minutes to two hours, and are often but not always gone by the morning. [2] Typically, the pains appear once or twice each week, but it can be more frequent or less frequent. [2]
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. [1]
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. [2] [3]
Theories of causation include:
Some parents are able to associate episodes of pain with physical exercise or mood changes in the child. [4]
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. [2] When the child has the typical symptoms and appears to be healthy, then laboratory investigations to exclude other diagnoses is not warranted. [2] [4] [3]
When a child has growing pains, there are no objective clinical signs of inflammation, such as swollen joints. Children with growing pains do not have signs of any systemic diseases (such as fever or skin rashes), any abnormal pain sensations, tender spots, or joint disorders. [1] 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. [2] 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. [2] [3] 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). [2]
Parents and children can be substantially reassured by explaining the benign and self-limiting nature of the pains. [1] [3] Local massage, hot baths, hot water bottles or heating pads, and analgesic drugs such as paracetamol (acetaminophen) are often used during pain episodes. [1] [4] Twice-daily stretching of the quadriceps, hamstrings, and gastrosoleus muscles can make the leg pains resolve more quickly when it appears. [2]
Growing pains are not associated with other serious disease and usually resolves by late childhood. [2] Commonly, episodes of growing pains become less severe and less frequent over time, and many children outgrow them after one or two years. [2]
Frequent episodes are capable of having a substantial effect on the life of the child. [4]
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. [2] Individuals can vary markedly in when they experience growing pains.
Growing pains were first described as such in 1823 by a French doctor, Marcel Duchamp, and the cause was attributed to the growth process. [2] [5] A century later, mainstream medicine thought that the pains were caused by a mild case of rheumatic fever. [2]
A convulsion is a medical condition where the body muscles contract and relax rapidly and repeatedly, resulting in uncontrolled shaking. Because epileptic seizures typically include convulsions, the term convulsion is often used as a synonym for seizure. However, not all epileptic seizures result in convulsions, and not all convulsions are caused by epileptic seizures. Non-epileptic convulsions have no relation with epilepsy, and are caused by non-epileptic seizures.
Cerebral palsy (CP) is a group of movement disorders that appear in early childhood. Signs and symptoms vary among people and over time, but include poor coordination, stiff muscles, weak muscles, and tremors. There may be problems with sensation, vision, hearing, and speech. Often, babies with cerebral palsy do not roll over, sit, crawl or walk as early as other children. Other symptoms include seizures and problems with thinking or reasoning. While symptoms may get more noticeable over the first years of life, underlying problems do not worsen over time.
Legg–Calvé–Perthes disease (LCPD) is a childhood hip disorder initiated by a disruption of blood flow to the head of the femur. Due to the lack of blood flow, the bone dies and stops growing. Over time, healing occurs by new blood vessels infiltrating the dead bone and removing the necrotic bone which leads to a loss of bone mass and a weakening of the femoral head.
Tension headache, stress headache, or tension-type headache (TTH), is the most common type of primary headache. The pain usually radiates from the lower back of the head, the neck, the eyes, or other muscle groups in the body typically affecting both sides of the head. Tension-type headaches account for nearly 90% of all headaches.
Familial Mediterranean fever (FMF) is a hereditary inflammatory disorder. FMF is an autoinflammatory disease caused by mutations in Mediterranean fever gene, which encodes a 781–amino acid protein called pyrin. While all ethnic groups are susceptible to FMF, it usually occurs in people of Mediterranean origin—including Sephardic Jews, Mizrahi Jews, Ashkenazi Jews, Assyrians, Armenians, Azerbaijanis, Druze, Levantines, Kurds, Greeks, Turks and Italians.
Genu valgum, commonly called "knock-knee", is a condition in which the knees angle in and touch each other when the legs are straightened. Individuals with severe valgus deformities are typically unable to touch their feet together while simultaneously straightening the legs. The term originates from the Latin genu, 'knee', and valgus which means "bent outwards", but is also used to describe the distal portion of the knee joint which bends outwards and thus the proximal portion seems to be bent inwards.
Spondylosis is the degeneration of the vertebral column from any cause. In the more narrow sense it refers to spinal osteoarthritis, the age-related degeneration of the spinal column, which is the most common cause of spondylosis. The degenerative process in osteoarthritis chiefly affects the vertebral bodies, the neural foramina and the facet joints. If severe, it may cause pressure on the spinal cord or nerve roots with subsequent sensory or motor disturbances, such as pain, paresthesia, imbalance, and muscle weakness in the limbs.
Flat feet, also called pes planus or fallen arches, is a postural deformity in which the arches of the foot collapse, with the entire sole of the foot coming into complete or near-complete contact with the ground. Sometimes children are born with flat feet (congenital). There is a functional relationship between the structure of the arch of the foot and the biomechanics of the lower leg. The arch provides an elastic, springy connection between the forefoot and the hind foot so that a majority of the forces incurred during weight bearing on the foot can be dissipated before the force reaches the long bones of the leg and thigh.
Intermittent claudication, also known as vascular claudication, is a symptom that describes muscle pain on mild exertion, classically in the calf muscle, which occurs during exercise, such as walking, and is relieved by a short period of rest. It is classically associated with early-stage peripheral artery disease, and can progress to critical limb ischemia unless treated or risk factors are modified and maintained.
Claudication is a medical term usually referring to impairment in walking, or pain, discomfort, numbness, or tiredness in the legs that occurs during walking or standing and is relieved by rest. The perceived level of pain from claudication can be mild to extremely severe. Claudication is most common in the calves but it can also affect the feet, thighs, hips, buttocks, or arms. The word claudication comes from Latin claudicare 'to limp'.
Hypermobility, also known as double-jointedness, describes joints that stretch farther than normal. For example, some hypermobile people can bend their thumbs backwards to their wrists and bend their knee joints backwards, put their leg behind the head or perform other contortionist "tricks". It can affect one or more joints throughout the body.
Periodic fever syndromes are a set of disorders characterized by recurrent episodes of systemic and organ-specific inflammation. Unlike autoimmune disorders such as systemic lupus erythematosus, in which the disease is caused by abnormalities of the adaptive immune system, people with autoinflammatory diseases do not produce autoantibodies or antigen-specific T or B cells. Instead, the autoinflammatory diseases are characterized by errors in the innate immune system.
Transient synovitis of hip is a self-limiting condition in which there is an inflammation of the inner lining of the capsule of the hip joint. The term irritable hip refers to the syndrome of acute hip pain, joint stiffness, limp or non-weightbearing, indicative of an underlying condition such as transient synovitis or orthopedic infections. In everyday clinical practice however, irritable hip is commonly used as a synonym for transient synovitis. It should not be confused with sciatica, a condition describing hip and lower back pain much more common to adults than transient synovitis but with similar signs and symptoms.
Unequal leg length is often a disabling condition where the legs are either different lengths (structurally), or appear to be different lengths, because of misalignment (functionally).
Hereditary sensory and autonomic neuropathy (HSAN) or hereditary sensory neuropathy (HSN) is a condition used to describe any of the types of this disease which inhibit sensation.
Angioleiomyoma of the skin is thought to arise from vascular smooth muscle, and is generally acquired. Angioleiomyomas appear as small, firm, movable, slow growing subcutaneous nodules. Pain is a common symptom. They are most commonly seen on the extremities. The cause of angioleiomyoma is unknown.
Spastic cerebral palsy is the type of cerebral palsy characterized by spasticity or high muscle tone often resulting in stiff, jerky movements. Cases of spastic CP are further classified according to the part or parts of the body that are most affected. Such classifications include spastic diplegia, spastic hemiplegia, spastic quadriplegia, and in cases of single limb involvement, spastic monoplegia.
Abdominal migraine(AM) is a functional disorder that usually manifests in childhood and adolescence, without a clear pathologic mechanism or biochemical irregularity. Children frequently experience sporadic episodes of excruciating central abdominal pain accompanied by migrainous symptoms like nausea, vomiting, severe headaches, and general pallor. Abdominal migraine can be diagnosed based on clinical criteria and the exclusion of other disorders.
Alternating hemiplegia is a form of hemiplegia that has an ipsilateral cranial nerve palsies and contralateral hemiplegia or hemiparesis of extremities of the body. The disorder is characterized by recurrent episodes of paralysis on one side of the body. There are multiple forms of alternating hemiplegia, Weber's syndrome, middle alternating hemiplegia, and inferior alternating hemiplegia. This type of syndrome can result from a unilateral lesion in the brainstem affecting both upper motor neurons and lower motor neurons. The muscles that would receive signals from these damaged upper motor neurons result in spastic paralysis. With a lesion in the brainstem, this affects the majority of limb and trunk muscles on the contralateral side due to the upper motor neurons decussation after the brainstem. The cranial nerves and cranial nerve nuclei are also located in the brainstem making them susceptible to damage from a brainstem lesion. Cranial nerves III (Oculomotor), VI (Abducens), and XII (Hypoglossal) are most often associated with this syndrome given their close proximity with the pyramidal tract, the location which upper motor neurons are in on their way to the spinal cord. Damages to these structures produce the ipsilateral presentation of paralysis or palsy due to the lack of cranial nerve decussation before innervating their target muscles. The paralysis may be brief or it may last for several days, many times the episodes will resolve after sleep. Some common symptoms of alternating hemiplegia are mental impairment, gait and balance difficulties, excessive sweating and changes in body temperature.
Benign acute childhood myositis (BACM) is a syndrome characterized by muscle weakness and pain in the lower limbs that develop in children after a recent viral illness. It is transient with a spontaneous clinical resolution within 1 week.
