What is the treatment for a pulled muscle in the arm?

Treatment for a Pulled Muscle in the Arm

For a pulled muscle in the arm, first aid should include rest, ice application for 20-30 minutes, and limiting activities that cause pain to promote optimal healing and recovery.

Initial Management (First 24-48 Hours)

• Apply cold therapy (ice wrapped in a damp cloth) to the injured area for 20-30 minutes, 3-4 times daily to reduce pain and swelling 1
• Rest the injured arm and avoid activities that cause pain to prevent further damage 1
• Limit use of the injured extremity until pain subsides 1
• Consider applying a compression wrap to promote comfort, ensuring it doesn't compromise circulation 1
• Elevate the arm when possible to help reduce swelling 2

Pain Management

• Over-the-counter pain relievers can be used for symptom control:
  • Acetaminophen (up to 4g/day) is recommended as first-line oral analgesic due to its safety profile 1
  • Topical NSAIDs can be effective for localized pain with fewer side effects than oral medications 1
  • Oral NSAIDs may be used at the lowest effective dose and for the shortest duration if acetaminophen is inadequate 1

Rehabilitation Phase (After Acute Pain/Swelling Subsides)

• Begin gentle range of motion exercises within pain limits once acute symptoms improve 1, 2
• Gradually introduce strengthening exercises to restore muscle function 1, 2
• Eccentric strengthening exercises (where the muscle lengthens while contracting) are particularly beneficial for muscle strain recovery 2
• Progress activity gradually to avoid re-injury 2

When to Seek Medical Attention

• If the pain is severe or worsening despite initial treatment 1
• If there is significant swelling, bruising, or deformity 1
• If arm appears blue or extremely pale (indicates possible vascular compromise) 1
• If you're unable to move the arm or have significant weakness 1
• If symptoms don't improve within 7-10 days of home treatment 1

Common Pitfalls to Avoid

• Applying ice directly on skin (can cause cold injury) - always wrap in a damp cloth 1
• Returning to full activity too soon (can lead to re-injury) 2
• Overusing heat in the acute phase (may increase swelling) 1
• Immobilizing the arm completely for prolonged periods (can lead to stiffness and muscle atrophy) 2
• Ignoring pain during rehabilitation exercises (exercises should be performed within pain limits) 2

Most muscle strains heal completely with appropriate treatment, though more severe strains may take several weeks to months for full recovery 3, 2.
