Chest pain lasting for five months requires urgent medical evaluation rather than self-medication. Because chest pain can stem from serious conditions involving your heart, lungs, or digestive system, it is unsafe to take any medicines without a proper diagnosis. I strongly advise you to see a doctor or cardiologist immediately. They will perform essential tests, such as an ECG or blood work, to identify the exact cause and prescribe the correct treatment. If your chest pain is ever accompanied by shortness of breath, sweating, dizziness, or pain radiating to your arm or jaw, please seek emergency medical care immediately.
