<s>[INST] I woke from sleep this morning with sharp pains that started in my chest and went into my upper back between shoulder blades,my arm pits and all the way to my wrist, it felt like my veins were exploding, I have never experienced this before and am really worried [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Sudden onset chest pain in morning is seen mostly with heart diseases. So better to consult doctor and get done blood pressure monitoring, ECG, 2d echo and stress test (trade mill test). You may need cardiac Chat Doctor. If all these reports are normal then no need to worry about heart diseases. Avoid stress and tension, be relaxed and calm.Don't worry, you will be alright but first rule out heart diseases. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
