yesterday, dec 30, i started to feel pressure in my gut, with nausea, no vomiting, but feel as tho' i could, gassy. burping and the rest

, the thought of food make me gag. I have had my flu shot a month ago. I'm 62, and a diabetic, and have RA. I take a lot of meds. My doc found that I am leaking blood somewhere and is arranging for me to have an endoscopy and a colonoscopy but I have felt fine until yesterday. I still feel lousy today. Unfortunately, my husband still thinks he needs to eat

. The pressure goes up into my upper back between my shoulder blades, not terrible just uncomfortable. I feel better if I am laying down, who doesn't? This is New Years Eve, does anyone have any suggestions as to what this could be?
