<s>[INST] Hello Lately everytime I have something to eat my stomach hurts almost instantly it seems. It s really painful in upper abdomin at first and after a few hours it is like my lower abdominal area is burning. I have been having stool with black specks throughout and I have also been exsperiance very abnormal spotting. [/INST] Hi. Thanks for your query and an elucidated history. Instant pain on eating is definitely suggestive of Gastritis or stomach cancer or HERD and so on. This can be diagnosed well by upper GI Endoscopy. In addition, you need a CT scan of the abdomen to rule out gastrointestinal Cancer, to see the status of the liver, pancreas and other organs of the abdomen. The treatment will solely be dependent upon the findings </s>
