Does anyone ever feeling like their heart is gurgling? Like if you have a congested chest and your breathing feels gurgly, like that, but in your heart. Does anyone know what could cause this? It doesn't last just a few seconds, it can last for a while, but sometimes if I change my sitting position it stops. It only ever happens where my heart is, not in other spots on my chest, which makes me think it's specific to my heart and not my chest.
