Which remedy has pain that improves with motion and warmth after initial stiffness, with restlessness and compulsion to move?

• A. Rhus toxicodendron
• B. Bryonia
• C. Natrum muriaticum
• D. Hepar sulfuris

Answer: (A)

This is the Rhus toxicodendron pattern: a stiffness that starts from overexertion or a chill, followed by pain that improves with motion and with warmth. The key is relief after moving and the need to keep moving—a restless, compulsion-to-move quality that drives the patient to get up and keep active despite the stiffness. Heat often helps, and the overall tendency is to seek motion as the remedy for discomfort.

This fits better than the others because Bryonia tends to have pains that worsen with motion and improve with rest, with a strong desire to stay still. Natrum muriaticum or Hepar sulfuris don’t match this specific combination of initial stiffness followed by relief from continued movement and warmth, along with marked restlessness.
