Hello, I ve been packing and moving boxes over the past few weeks. In the past 3 or 4 days, though, I ve noticed that the very top of my abdomen, just under the sternum and for about 6 inches lower on the right side, a feeling of pressure and fullness, especially after eating or sitting. At night, it is uncomfortable (slightly achy, not really pain) to lie on either side as it feels as I m compressing something. I ve also noticed some reflux type symptoms at night when I lie down. Could I possibly have a hernia that high up? I am a 50 year old female, 5 7 , 175 lbs. Thank you.
