Arm Pain in an 8-Year-Old: Causes and Next Steps - Pediatrics

Share to:

An 8-year-old girl experiences intermittent pain in her right arm, and during episodes of pain, she sometimes feels weakness in her legs?


Hello, my daughter is currently 8 years old.
Since she fell last year, she has been experiencing persistent pain in her arm, and sometimes this pain is accompanied by weakness in her legs.
She has undergone blood tests, an EEG, and X-rays with an orthopedic specialist, all of which showed no abnormalities.
Recently, the frequency of her pain has been increasing.
The doctor prescribed a topical analgesic, but the effect has not been significant.
Could this be growing pains, a muscle strain, or another condition? Which specialist should I take her to see? Thank you!

Dr. Xiao Kaiwen reply Pediatrics


Growing pains in children typically occur at night and usually affect both lower limbs, so your child may not be experiencing this.
A simple muscle strain is unlikely to last this long.
There is a rare but serious condition in children called juvenile idiopathic arthritis, which has specific diagnostic criteria.
Given that your child's symptoms have persisted for a while, it is advisable to visit a major hospital and consult a pediatric rheumatologist to rule out this condition.
If it is not juvenile idiopathic arthritis, the physician can then evaluate the possibility of other diseases and refer to other subspecialty physicians as needed.

More Info


Understanding arm pain in an 8-year-old can be quite complex, especially when previous medical evaluations have ruled out serious conditions. Given your daughter's history of falling and the subsequent onset of pain, it is essential to consider various potential causes and the appropriate next steps.


Possible Causes of Arm Pain
1. Growth Pains: Growth pains are common in children, typically occurring in the late afternoon or evening and often affecting the legs more than the arms. However, they can manifest in different areas, including the arms. These pains are usually not associated with any physical activity and tend to resolve on their own.

2. Muscle Strain or Overuse: If your daughter has been engaging in activities that require repetitive arm movements or if she has been more active than usual, muscle strain could be a possibility. This can lead to discomfort and a feeling of weakness in the arm.

3. Nerve Issues: Conditions such as thoracic outlet syndrome or brachial plexus injuries can cause pain and weakness in the arm. These issues may arise from trauma or repetitive stress.

4. Referred Pain: Sometimes, pain in one area can be referred from another part of the body. For instance, issues in the neck or shoulder can manifest as arm pain.

5. Psychosomatic Pain: Children sometimes experience pain that is not linked to a physical cause but rather to emotional stress or anxiety. This is particularly relevant if the pain has increased in frequency without a clear physical cause.

6. Other Medical Conditions: While less common, conditions such as juvenile idiopathic arthritis or other inflammatory diseases could cause persistent pain.

Next Steps
Given that your daughter has already undergone several tests, including blood tests and X-rays, and has been evaluated by an orthopedic specialist, it may be beneficial to consider the following steps:
1. Consult a Pediatrician: Since your daughter is experiencing increasing pain, it would be wise to revisit her pediatrician. They can conduct a thorough assessment and determine if further evaluation is necessary.

2. Physical Therapy: If muscle strain or overuse is suspected, a referral to a physical therapist could be beneficial. They can provide exercises to strengthen the muscles and improve flexibility, which may alleviate pain.

3. Pain Management: If the topical pain relief has not been effective, discuss alternative pain management strategies with your healthcare provider. This could include oral medications or other topical treatments.

4. Monitor Symptoms: Keep a detailed log of when the pain occurs, its intensity, and any associated activities. This information can be invaluable for healthcare providers in diagnosing the issue.

5. Consider a Rheumatology Consultation: If there is a suspicion of an inflammatory condition, a referral to a pediatric rheumatologist may be warranted. They specialize in diagnosing and treating autoimmune and inflammatory diseases in children.

6. Emotional Support: If psychosomatic pain is a concern, consider speaking with a child psychologist or counselor who can help address any underlying emotional issues.


Conclusion
In conclusion, while growth pains are a possibility, the increasing frequency and intensity of your daughter's arm pain warrant further investigation. A multidisciplinary approach involving pediatricians, physical therapists, and possibly rheumatologists can help identify the underlying cause and provide appropriate treatment. It is essential to advocate for your child's health and ensure that her concerns are taken seriously. Regular follow-ups and open communication with healthcare providers will be key in managing her symptoms effectively.
