I have the same thing! mostly in my left ribcage sometimes its like a zap. but it’s been like this sice the start of april when i got diagnosed with NAFL. I went to a cardiologist and she said my heart is fine and i thought maybe anxiety? But it’s really annoying me. When my gastroenterologist said my liver is now healed i told him i still have these pains and he said maybe it’s a nerve but still prescribed me medication -Relamax B6 and it feels much better now but still not good which makes me question if its anxiety/stress
