I've been having chest and upper back pain for about 34 months now. I've done the ECG twice, and the results were normal, and my X-ray showed nothing unusual. But the pain keeps spreading more and more each day and can start or stop at any time. I don't have cough, fever, or vomiting or anything like that. What could be causing this, and what should I do about it?

take tablet zerodol and tablet pantop for 3 days
