I had this issue in 1999 I consulted a gastroenterologist and he diagnosed it as gut hypomotilty issue and prescribed a tablet Normagut ( Cisapride + Methyl Poly Siloxane ).
Ask for Mozapride with MPS from your gastro. The symptoms should vanish in a week's time. Also ask your gastro or PCP for a neurologist consult. In my case it was diagnosed as epigastric aura. I am taking Torleva (levetiracetam ) and lonazep (Clonazepam) Ask for a epilepsy MRI scan and EEG scan. Hoping itis just gut dysmotility.
