I've been having this weird pain, like in my heart and behind it, and it's been slowly moving to my shoulder. Now my mouth is super dry and I'm even feeling some pain near the top part of my left arm, right above my heart. What could this mean? Should I be worried about these symptoms?
It sounds like you may be experiencing symptoms of a heart attack. It is important to seek immediate medical attention. In the meantime, you can take a tablet of aspirin (325mg) to help thin the blood and reduce the risk of further complications. Call emergency services or go to the nearest hospital as soon as possible for proper evaluation and treatment.
