Detailed Answer:
Hello,

Welcome to Healthcare Magic.

I read carefully your query and understand your concern.

Black stools are very indicative for a gastrointestinal bleeding .Most likely it is an upper gastrointestinal bleeding,and it is called melena.
Associated this with this left flank pain (left waist) is suggestive for a gastointestinal lesion.It might be angioectasia in colon,diverticulitits ,kidney stones etc.This makes really necessary a consult with an hematologist doctor as soon as possible.

If you have back stools very often and the pain in your waist is recent ,you may need to go to ER for treatment if you can't find another doctor very soon.

This requires a specific treatment and a detailed examination to determine the
cause of GI bleeding in your case.


Hope it helps.
Let me know if you have any other question or doubt to clarify.I will be happy to assist you further.

Kind regards,
Dr.Rovena Murati
