Heart Attack
Another potential medical emergency that can stem from hand numbness is a heart attack. That said, it’s even more unlikely to be from hand numbness, though there is a specific situation where it could potentially be a heart attack. For example, a heart attack is caused by a blocked coronary artery. The blockage will lead to a lack of blood flow, characterized by numbness in the left arm. If it isn’t just your hand that’s numb but your left arm, alongside a few other potential symptoms, then making an emergency call is a good idea, as time is of the essence. Otherwise, it’s likely that hand numbness isn’t a symptom of a heart attack.
Another symptom of a potential heart attack is pain around the jaw, neck, or back. The most common symptom of a heart attack is chest pain. You might also have shortness of breath or are feeling weak or light-headed. If ever you’re feeling these symptoms, have someone drive you to the nearest hospital or make an emergency call. If it’s only hand numbness, consider other causes.
