Yeah, please never never never mistake what a bunch of large adult children say on the Internet (especially the ones who are so online we have green symbols next to our names holy shit) for medical advice. That would, by far, be the easiest way to parody yourself. For anything we might suggest, a doctor or a physical therapist would probably have a better handle on what it means to deal with your heart problem. Stay safe, know the difference between good pain & bad pain, and have somebody knowledgeable and/or something to help with emergencies.
