With the symptoms worsening on exertion (jogging) and goes away at rest, this is suspicious for coronary artery disease. However, you mentioned negative stress testing 3 years ago. Before attributing it to a GI cause, the heart has to be conclusively ruled out. Repeating the cardiac stress testing should be considered.
If the heart has been ruled out, the GI causes can be pursued. An upper endoscopy or upper GI series would be reasonable tests in going this route.
You can discuss this with your personal physician.
Followup with your personal physician is essential.
