What arm hurts when you have a stroke?

When a stroke occurs, it can cause weakness or numbness in one side of the body, often affecting the arm on the side opposite to where the stroke occurred in the brain. For example, if a stroke affects the right hemisphere of the brain, the left arm may experience pain, weakness, or difficulty moving. This symptom is part of a broader set of signs, commonly referred to as F.A.S.T. (Face drooping, Arm weakness, Speech difficulties, Time to call emergency services). Immediate medical attention is crucial when these symptoms arise.
