Nuclear stress test results came back normal. however, i'm still feeling symptoms. am i just being dumb? should i just be content w/the results?

Not Dumb.: If the stress test test is negative, you still need to find why you are having symptoms. All you have done is found a reason you are not having them.

See below: It is not feasible to provide a meaningful opinion without taking additional history, physical examination and may be some tests. It would be prudent to see your doctor and discuss if you may be depressed. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated.
