Psychomotor agitation is when someone feels very restless and can’t sit still. This might show up as things like pacing, fidgeting, or tapping their fingers or feet. It often happens when a person feels anxious, upset, or overwhelmed, and their body seems to be “on edge.” The person might have trouble relaxing and could appear tense or overly energetic, even though they’re struggling emotionally. It’s a physical way the body responds to stress or strong emotions.
