<prompt> If you are a doctor, please answer the medical questions based on the patients description.58 yr old male. Been having a fairly constant flutter in what appears to be my upper left portion of my stomach. No pain or other gas related symptoms. It is just annoying. Usually I can even see the movement on my stomach wall. Been going on sporadically for about a month now.  <response>: Hi, Further details are needed to a better judgement: - does the fluttering sensation appears after eating or after doing any other physical activity?- are you also having shortness of breathe?- any other symptom nausea, changes in bowel movements? The constant fluttering sensation could be related to: - gastric problems HERD, gastritis- heart problems arrhythmia- neurological problemsFurther investigations are needed: - upper endoscopy-abdominal ultrasound-EKG- Holder monitoring-stress test- Ct-scan of spinal cord thoracic and lumbar sectionHope it helped!
