I am also happy to know that the cardiac and neurological tests you did result all normal. As you have ongoing upset stomach problems, I highly recommend consulting with GI specialist and to run upper endoscopy to evaluate your stomach and other GI organs to determine the right cause and start proper treatment. My thoughts go for possible: gastritisHERD or ulcer issues that should be determined. In regard to slight head pain and bouts of imbalance, I recommend to:- consult with ENT specialist to rule out inner ear issues-measure your blood sugar and blood pressure, record the results for future evaluation by your doctor hypoglycemia and hypotension should be ruled out. For the moment, I advise watching what you eat and observe what effect they have on your actual stomach problems. Avoid those that would aggravate your symptoms. Hope it was of help! Chat Doctor.
