The weird beating seems like my heart is either beating normally or weakly and then there's a "hiccup" every minute or so. When I lay down with my ear against the pillow when this happens, I can hear my blood flow, which seems weird, like my blood containing tubes/pump is wider than the amount of liquid in the chambers; like an echo-y water flow sound.
Part of me thinks this is the L-arginine I take (to get "swoll" as they say) combined with the amount of caffeine I take in? Another part of me thinks this is a valve issue from bacterial endocarditis, since I still have my wisdom teeth, though I brush 3+x/day, but I've had 2 splinter hemorrhages without trauma on my fingernails recently, though I like any signs of Osler nodes.
I'm 6'1", 184-ish, muscular build, so maybe it's all in my head and the above paragraphs are the result of hypochondria exacerbated by a lack of health insurance or the money to even pay for a routine doctor's visit. I mean, I eat all healthy homemade food; currently cooking black beans + garbonzo beans to make a hummus of sorts.
Hoping my anxiety stays tempered long enough for me to get back on my feet while finishing my current project.
EDIT: I forgot to mention a frequent shortness of breath, though like in Jason Scott's case, this doesn't seem to prevent me from physical activity, but it bothers me that I can't take deep breathes all the time.
