Cardiac. You need to rule out cardiac nature of your pain. See physician as soon as possiable. Consider er.
As. As your pain has been that persistent you should get evaluated medically, especially as your pain did not improve with medications. Do not take any medications like advil, (ibuprofen) smoke, or use alcohol as they can irritate your stomach. But as your pain has lasted this long you need to be seen. If you have severe pain, vomiting, or fever then you must be seen as an emergency.
