Hello, the green stool and the pus from the belly do not seem to be related to each other. If the discharge is coming out of your umbilicus (the belly button) then this is omphalitis and has various causes. The exact cause can usually be identified with either an ultrasound scan or a CT scan. The treatment is surgical but it also requires administration of antibiotics. In mild cases antibiotics only and drainage may resolve it. If it s not the umbilicus then it s most likely a superficial infection or inflammation (carbuncle, infected cyst, etc). The treatment is the same. Green stool means faster passage of the intestinal content through the intestinal lumen. There are far too many causes to mention here. The most common ones is the patient s diet. Certain foods may stain the stool and make them look green. Iron supplements make the stool dark green (may look like black sometimes). Various causes of diarrhea may also cause green stools. More information is required for the investigation of this problem. I ll be glad to provide more clues, if you send more information about the quantity, consistency of the stool, how many bowel movements you have per day and the rest of your symptoms. Uploading any tests you ve done will help a lot. I hope you find my comments helfpul! You can contact me again, if you d like any clarification or further information. Kind Regards!
