Do a recent c5-c6 herniated disc with spondylosis and l5-s1 prolapse disc with spondylosis cause symptoms similar to heart attack?chest pain& fatigue

Not usually. See MD: A cervical disc on the left can cause pain in to left shoulder/scapula and in to the arm. The pain can give a patient fatigue if sleep is impaired. The heart should definitely be evaluated as soon as possible, though, as that could be potentially be life-threatening.

Possibly: The low back finding could not cause such symptoms, but a c5-6 disc herniation could potentially cause symptoms similar to a heart attack, such as left shoulder and arm pain. Good question.
