WHEN TO CALL YOUR DOCTOR

HOME CARE ADVICE FOR OVERUSE INJURY (STRAINED MUSCLES)

1. Reassurance:
   • Strained muscles are very common following vigorous activity (overuse injury) (e.g., repeatedly throwing a ball). We can treat them at home.
   • 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.
2. Pain: For pain relief, give acetaminophen every 4 hours OR ibuprofen every 6 hours as needed. (See Dosage table)
3. Hot Bath: If stiffness persists over 48 hours, have your child relax in a hot bath for 20 minutes 2 times per day, and gently exercise the involved part under water.
4. Expected Course: A strained muscle hurts for 2 or 3 days. The pain often peaks on day 2. Following severe overuse, the pain may last a week.
5. Call Your Doctor If:
   • Swollen joint or fever occurs
   • Pain caused by work or exercise persists over 7 days
   • Pain becomes worse

And remember, contact your doctor if your child develops any of the "Call Your Doctor" symptoms.
