"Im not sure about the endoscopy because its invasive and im worried either way"
Holds1325 I can relate to this : I was rush to my ER- ICU hospital for 3 1/2 days last weekend ,the G.I. doctor used this Upper gastrointestinal (GI) endoscopy
to determine why I was losing 2 pints of blood a day (for the last three days) thru my digestive track, over time alcohol , aspirin , spicy food ,etc completely ulcerated my stomach, the endoscopy was used to see this issue, before surgery and a massive blood transfusion could begin.
I hope you get thru this ok , don't wait get checked out by your doctors.
I waited to the last minute, and I could actually feel death at my doorstep.
