- Pain in the legs
- The pain is not due to a known injury
- Minor muscle strain and overuse injury are covered in this topic
- Main Causes: Muscle spasms (cramps) and strained muscles from overuse injury (e.g., excessive running or jumping). Up to 50% of all injuries seen in pediatric sports medicine are related to overuse.
- Muscle Cramps: Brief pains (1 to 15 minutes) are usually due to muscle spasms (cramps). Foot or calf muscles are especially prone to cramps that occur during exercise or that awaken your child from sleep. Muscle cramps that occur during exercise are also called heat cramps. They often respond to extra water and salt.
- Strained Muscles: Continuous acute pains (hours to 3 days) are usually due to overstrenuous activities or forgotten muscle injuries during the preceding day. Can occur in arms or legs.
- Growing Pains: 10% of healthy children have intermittent, harmless pains that are often referred to as growing pains (although they have nothing to do with growth)
- Viral Infections: Muscle aches are common with viral illness, especially influenza.
- Serious Causes: Fractures, swollen joints (arthritis), deep vein thrombosis, neuritis

Home Care Advice for Muscle Cramps or Strained Muscles
- Treatment For Muscle Cramps:
- Muscle cramps in the feet or calf muscles occur in a third of children.
- During attacks, stretch the painful muscle by pulling the foot and toes upward as far as they will go to break the spasm.
- Stretch the muscle in the direction opposite to how it is being pulled by the cramp or spasm.
- Apply a cold pack or ice bag wrapped in a wet cloth to the painful muscle for 20 minutes.
- If these are heat cramps (occurring during exercise on a hot day), give lots of water and sports drink in addition to stretching the muscle and a cold pack.
- Future attacks may be prevented by daily stretching exercises of the heel cords (stand with the knees straight and stretch the ankles by leaning forward against a wall). Also give the feet more room to move at night by placing a pillow under the covers at the foot of the bed. Also be sure your child gets enough calcium in the diet.
- Treatment For Strained Muscles From Excessive Use (Overuse Injury):
- Apply a cold pack or ice bag wrapped in a wet cloth to the sore muscles for 20 minutes several times on the first 2 days.
- Give acetaminophen (e.g., Tylenol) or ibuprofen for pain relief.
- If stiffness persists over 48 hours, have your child relax in a hot bath for 20 minutes twice a day, and gently exercise the involved part under water.
- Expected Course: Muscle cramps usually last 5 to 30 minutes. Once they resolve, the muscle returns to normal quickly. A strained muscle hurts for 2 to 7 days. The pain often peaks on day 2. Following severe overuse, the pain may last a week.
- Call Your Doctor If:
- Muscle cramps occur more frequently
- Child develops a limp, a swollen joint, or a fever
- Pain caused by work or exercise persists over 7 days
- Your child becomes worse
And remember, contact your doctor if your child develops any of the "Call Your Doctor" symptoms.
