I'm feeling really anxious about some things I've noticed. My recent ECG showed some non-specific T wave changes, and I'm not sure what that means. On top of that, I've been dealing with chronic pain in my left arm and I've also been experiencing tachycardia. Should I be worried about these symptoms together? Any advice or insights would be really helpful.

Non-specific T wave changes on an ECG can have various causes, including cardiac issues, electrolyte imbalances, or even be a normal variant. Given your symptoms of chronic left arm pain and tachycardia, it is important to further evaluate the underlying cause. In this case, you may benefit from a thorough cardiac evaluation and possibly a medication like Aspirin for heart protection, along with a beta-blocker like Metoprolol to help control your heart rate. Additionally, addressing any underlying issues such as high blood pressure or cholesterol levels may also be necessary. It is important to follow up with your healthcare provider for further assessment and management.
