For the past few months, I have had a strange sensation (skin crawling, pins-and-needles) in my lower left abdomen. Usually, it happens after eating a large meal, but also when I am under stress or lying down in a certain position. After an upper G.I., my doctor told me that the only thing that showed up was a mild inflammation of my duodenum he called duodenitis that could be related to irritable bowel syndrome or GERD. He could be right, but I can't find anything about this strange symptomology anywhere. Any help would be appreciated!
