Hi, I had gone through your question and understand your concerns. You should be worried but not too much. Firstly the abdominal fluttering could be due to irritation of peripheral nerves. An EMG test will be helpful in diagnosing it. The other possibility is that these sensations are mild seizures. Also upper right abdominal area is where the gallbladder and stomach can give symptoms. So in case of gallstones or peptic ulcer you may have upper middle or right abdominal pain or discomfort. The symptoms are triggered by a food. I would suggest you to perform ultrasound and consult an experienced neurologist,physician about it. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
