Hi.
Thanks for your query.
Noted the history and understood your concerns.
Green stool with black specks, then
blood in stool, pain in abdomen is indicative of severe intestinal infection.
I would advise you hte following in such a situation:
Go to ER or get hospitalized as this can lead to gram negative septicemia and multiorgan failure if not found and treated in time.
You needs tests of stool, culture and sensitivity.
Blood: CBC, culture and sensitivity, liver, kidney functions.
X-ray and CT scan of the abdomen.
A course of antibiotic and
metronidazole.
Probiotics and symptomatic treatment.
Intravenous fluid and electrolyte supplements.
Colonoscopy at a later date if indicated.
