Hi,Dear,Thanks for your query to HCM.
Dear I read your query and reviewed it with context to your query facts.
I understood your health concerns and feel Concerned about them.
Based on the facts of your query, you seem to suffer from-
Upper GI Bleeding-which needs further investigations.
AS you already had normal USG/ and testicle,
With only black stools with right
abdominal pain and
back pain with testes pain,you mostly seem to have-Bleeding in the Upper GI-.
Many causes of this black stool-like Ca-Pancreas,Duodenal/Gastric Ulcer,
Association of Right
testicle pain,could be only explained, by the irritation of the neurovascular testes bundle draining in the right iliac vein or
Inferior Vena Cava,from inflammed( intestines/cancer colon) bowels around.
Its very difficult to assess your testical pain with back and right lower abdominal pain,with the limited facts submitted by you.
Hence Consult GI-Endoscopist who would do EGD(Esophago-Gastro-Duodenoscopy) for
second opinion.
As I don't have more clinical / physical findings, Second Opinion from GI specialist / Urologist-Specialist,who would investigate your case after proper investigations.
Hope this would help you to solve your health issues in the best way possible.
Welcome for any further query in this regard.
Good Day!!
