Arm Pain

Arm pain can arise from numerous sources throughout the upper extremity, from the shoulder joint to the fingertips. While often caused by muscle strains, injuries, or overuse, arm pain can also signal serious conditions like heart attacks or nerve compression. Understanding the location, quality, and associated symptoms of arm pain helps determine whether it's a minor issue that will resolve with rest or a medical emergency requiring immediate attention.

Quick Facts

  • Very common symptom
  • Multiple causes possible
  • Can signal heart problems
  • Location matters
  • Often treatable

⚠️ Seek Emergency Care Immediately If Arm Pain Occurs With:

  • Chest pain, pressure, or tightness (possible heart attack)
  • Shortness of breath or difficulty breathing
  • Left arm pain with jaw, neck, or back pain
  • Sudden severe pain with visible deformity
  • Arm paralysis or inability to move
  • Numbness spreading up the arm
  • Bone protruding through skin
  • Severe bleeding from arm injury
  • Signs of stroke (facial droop, speech problems)
  • Cold, pale, or blue arm
  • Rapid swelling with severe pain
  • Dizziness, nausea, or sweating with arm pain

Left arm pain with chest symptoms may indicate a heart attack. Call 911 immediately.

Understanding Arm Pain

The arm contains a complex network of bones, joints, muscles, tendons, ligaments, nerves, and blood vessels. Pain can originate from any of these structures or be referred from other areas, particularly the neck, shoulder, or heart. The arm includes the upper arm (humerus), elbow joint, forearm (radius and ulna), wrist, and hand, each susceptible to different types of injuries and conditions.

Arm pain characteristics provide important diagnostic clues. Sharp, sudden pain often indicates acute injury, while gradual onset suggests overuse or degenerative conditions. Burning or tingling pain typically involves nerve compression, whereas deep, aching pain may arise from bones or joints. The specific location - whether in muscles, joints, or following nerve pathways - helps narrow down potential causes.

One crucial consideration is that arm pain, particularly in the left arm, can be a symptom of heart disease. This referred pain occurs because the heart and arm share nerve pathways to the brain. While not all arm pain indicates heart problems, understanding when arm pain might signal a cardiac emergency can be lifesaving.

Nerve-Related Causes

Vascular and Cardiac

  • Heart attack: Left arm pain classic symptom

  • Infections: Cellulitis, abscess
  • Bone cancer: Primary or metastatic
  • Referred pain: From organs or spine

Associated Symptoms

Arm pain often occurs with other symptoms that help identify the cause:

  • Numbness/tingling: Nerve involvement
  • Weakness: Muscle or nerve damage
  • Swelling: Injury or inflammation
  • Stiffness: Joint or muscle problems
  • Redness/warmth: Infection or inflammation
  • Deformity: Fracture or dislocation
  • Chest pain: Cardiac involvement
  • Neck pain: Cervical spine issues
  • Shoulder pain: Related conditions
  • Hand symptoms: Grip weakness, dropping things
  • Skin changes: Color, temperature
  • Night pain: May indicate serious pathology

Diagnosis and Evaluation

Medical History

  • Pain onset and duration
