hello, my uncle is passing blood from the bowel, went to hospital and they told him that the nerves around the heart aren t just leaking, they are spraying blood . I don t know if he meant vessels or nerves, but said they didn t know what to do with him put him on a blood thinner and another script and sent him home. Now, I m not a Dr., not even a nurse, but I m pretty sure if they didn t know what to do, they should have called in a Cardiologist?
