I've done an ECG, echo, and TMT test recently, and while everything seems normal, I'm still feeling this burning or electric shock sensation in my left arm, neck, shoulder, and back. Sometimes it feels like my chest is being pinched, and it seems like whatever I eat gets stuck in my throat. I don't have major breathlessness, but the palpitations and anxiety are really kicking in. How long are these test results valid for? I'm pretty worried, and I'm unsure who I should consult next since the doctor said everything's fine and no treatment is needed. What should I do?

The tests you mentioned (ECG, echo, TMT) are typically valid for a short period of time, usually a few days to weeks. Since your symptoms are persisting despite normal test results, it's important to consider other possibilities. It sounds like you may be experiencing symptoms of anxiety or acid reflux, which can sometimes mimic heart-related issues. To help with the burning sensation in your left arm, neck, shoulder, and back, as well as the feeling of something stuck in your throat, you can try taking antacids like **Tums** (dosage: 2 tablets as needed) for relief. For the chest discomfort and palpitations, you can take **Atenolol** (dosage: 25-50mg once a day) to help with the palpitations and anxiety symptoms. However, it's important to consult with a cardiologist or a gastroenterologist for further evaluation and management of your symptoms. If your symptoms persist or worsen, it's important to seek further medical advice for a proper evaluation and treatment plan.
