HOME CARE ADVICE FOR ARM PAIN
Reassurance:
- Strained muscles are very common following vigorous activity (overuse injury) (e.g., repeatedly throwing a ball). You 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.
Pain Medicine: For pain relief, give acetaminophen OR ibuprofen as needed. (See Dosage table)
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.
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.
Call Your Doctor If:
- Swollen joint or fever occurs
- Pain caused by work or exercise persists over 7 days
- Pain becomes worse
