I'm starting to get really worried because my heart's been racing for the last day and a half. It's super uncomfortable and happens whether I'm sitting or standing. I'm not even exercising or anything, so I can't figure out what's causing it. What should I do?
It sounds like you may be experiencing episodes of tachycardia. It is important to consult a healthcare professional for a proper evaluation and diagnosis. In the meantime, you can take a beta-blocker medication like Metoprolol (25-50mg) to help slow down your heart rate and reduce the discomfort. Additionally, make sure to stay hydrated and avoid caffeine and stimulants which can exacerbate the symptoms. If the symptoms persist or worsen, seek medical attention promptly.
