I was diagnosed with inguinal neuralgia back in December 2016. The drugs Norco, Meloxicam, and Amitriptyline were prescribed. On January 22 this year, while hiking, I experienced severe chest pain, shortness of breath, and dizziness. Trip to cardiac ER and cardio tests (catheter, angiogram) indicated problem was left bundle branch block . My own doctors did not say anything at the time about possible cardio effects of the Amitriptyline and did not tell me to stop taking it. But my online searches have turned up several published articles on similar negative cardiac effects. Do you think my experience could have been a side effect of the Amitriptyline???
