the arm on the same side. That combination is especially concerning.
2. Sudden Arm Weakness
Arm weakness is one of the most recognized warning signs. The person may be unable to lift one arm, hold it steady, or grip objects normally.
Ask the person to raise both arms. If one arm drifts down, feels numb, or cannot move well, call emergency services.
This matters because weakness can reflect a problem with brain signals controlling movement. The faster the person receives medical evaluation, the better the chance of reducing serious complications.
