I am feeling, for about an hour now, as if there is a bubble in my abdomen midway and sort of left side. Ifeels as if it is full then deflates, repeats about 3 times. Then nothing for a few minutes and repeats. I don't feel pain or pressure, just very clearly feel the sequence. I am male, almost 68 years old, and overweight. Please reply to YYYY@YYYY Thank you
