I'm Dr. Nikhil Aggarwal, and I'm here to help you. I'm sorry to hear about your symptoms. While I can't diagnose you without a proper examination, I can provide you with some information. Gastritis is inflammation of the stomach lining, which can cause symptoms such as abdominal pain, bloating, nausea, and vomiting. However, the symptoms you're experiencing, such as needle-like pain in your left arm and chest, could potentially be related to your heart. Chest pain and arm pain can be symptoms of a heart-related issue, such as angina or a heart attack. It's important not to ignore these symptoms, especially if they are severe or persistent. I recommend seeking immediate medical attention by calling emergency services or going to the nearest emergency room. A healthcare professional will be able to evaluate your symptoms, perform a physical examination, and order any necessary tests to determine the cause of your symptoms. They may consider factors such as your medical history, risk factors for heart disease, and perform an electrocardiogram (ECG) to assess your heart's electrical activity. Remember, it's always better to err on the side of caution when it comes to chest pain. Prompt medical evaluation is crucial to rule out any serious underlying conditions.
