Hi, I'm 32 and occasionally it will feel like my heart itches. Another answer to a similar question here just came back with another question asking whether the itch was on the heart or on the chest, and that wasn't helpful. This itch really does feel like it's internal, "on the heart," and unreachable. Would it be related to the digestive system, like a "heartburn," or does it suggest something else? I'm slightly concerned but also curious. Thank you.
