What happens if i do got melena and don't do anything does it heal on its own?

This is serious, Ray: If you're having black, tarry stools, get to the emergency room NOW. If your stools are merely a little bit black and a little bit loose, get with your personal physician soon -- it's likely to be a bleeding ulcer. If your stools are merely black but well-formed, perhaps you've taken an iron pill or a bismuth tablet. How do you FEEL? Thanks for asking and hope this gets solved.
