Zach, please talk to your doctor about these medical concerns you have. You should have gotten your answers when you were hospitalized, but now that you are out and have questions, contact your doctor. We don't know you or your medical history. Your doctor does. Start there. Don't have strangers on the Internet give you medical advice.
