Well there are a few possibilities which do come to mind which ill go through below, first off you have HAD an endoscopy done, the upper GI is an endoscopy which showed the ulcer and dyspepsia. Now an ulcer can also sometimes flare up and cause pain like the one which you are describing and cause nausea and vomiting. It can even cause black colored stools as well as black colored vomitus in some cases. Since your last endoscopy was a year back and you have developed these symptoms in the last 3 months, it might be worthwhile looking into this some more and having the endoscpy repeated. Secondly at the same time, do get screened for H.Pyroli infections which can sometimes make the symptoms worse. It is easily treated with a course of antibiotics.
Next up, given the pain, dizziness, ringing ears i would also consider autonomic neuropathy as the cause for these symptoms. Autonomic neuropathy is a condition in which teh autonomic nervous system is damaged because of several underlying issues. This can cause fullness after eating, sweating after eating, dizziness on standing up, fluctuations in blood pressure as well as heart rate. This can also cause changes in bowel habits as well. The diagnosis can be confirmed by a number of tests which can include gastric motility studies, tilt table testing etc. The treatment depends on the underlying cause.
Now i was asking about the autoimmune disorders as you have symptoms involving multiple systems of the body and it is possible that autoimmune disorders are causing them. This would be checked with ANA and ESR and if needed a complete ENA profile. There are numerous disorders which can present in this manner.
Now if you have diarrhea alternating with constipation off and on then it may also be worthwhile to look into lower GI causes for your pain as well as the bowel symptoms. A colonoscopy may be worthwhile, sometimes these symptoms can also be a consequence of malabsorption syndromes which usually cause diarrhea but in the initial stages can cause alternating bowel habits(rarely). In addition if all other causes are ruled out then we should consider irritable bowel syndrome as a cause as well.
Appendicitis is less likely as it would not persist for 3 months and would have been picked up in teh CT scans of teh abdomen. this is more likely to be an intestinal or stomach related disorder.
i would suggest that you discuss these options with your doctor.
