hello and thank you for posting your medical question on e health forum. from the history provided dark stools and swelling in the arm pit are not related to each other. you might need to get some blood tests and a complete physical to know the exact cause of your symptoms. you might consider to consult your doctor for additional counselling. i hope this helps.
