Hello Muthaiah. I have had similar, but chronic symptoms as you have described. The intensity can be more episodic. I am interested in what you find out about yours, if you decide to share. I have to wait until July to get into gastroenterology. Have you heard of Sphincter of Oddi Dysfunction? It might be a direction to look at. I am hoping for an endoscopy to clarify the source of my symptoms, and maybe resolution or strategies to deal with the pain and nausea, and inability to digest certain food groups. I will be watching for any information here. Thankyou and good luck!!!
