I am a 45 yo f, BMI 19, very active, eat healthy, etc...I have what sounds like a very large gas bubble in my left upper quadrant that I can't feel (no pain) but it is extremely noisy when I breath and even louder when I lay on my right side. If I push in on it I feel and hear it even louder, when I release I feel and hear it move around even more. It is annoying and I have had it for months with no relief from gas-x etc... I thought maybe I had a lactose problem so I tried a lactase product a few months ago with no result. How do I get rid of it!
