I have been pretty good after last year when i got diagnosed with GERD, Jan, Feb i barely noticed it and stop taking drugs for it, i also specially last week started eating mexican food, indian, drank beer, i also took painkillers twice, well on Sat i felt some symptoms, but mainly fullness. Sunday I passed a black stool and again yesterday and again today. I am going to the doc tomorrow I have no other symptom, no weakness or dizzyness. Also, I got an endoscopy in early Jan and the doc said that it all looked good and healthy. Then i started feeling better, so i was sure it was fine. I got tested for ulcers too and came back neg, can't wait to see what's going on. It is very alarming all of a sudden
