I am suffering from stomach discomfort and nausea for one month, six years back i got an upper endoscopy and diagnosed that i have multiple erosions in duodenum .  now i have no pain but some discomfort like bloating , passing air and poop colour changes to a little dark and yesterday a little (veey little like 1 drop) sort of bright blood in it. so i'm worried what is happening to me....is this due to recurrance of duodenal ulcer or anything serious....i'm afraid of it coz i think if it is the symptom of stomach cancer. Is it possible to develop a duodenal ulcer to cancer at this age..? for 2 days i'm taking PantofixD and Lactic acid bacillus capsules 1 each together per day...now the symptoms improved...but i am confused and worried....i need some suggestions...please help me
