[|Human|] I have to go to a gi doctor because I have GERD , esophageal stricture spasms, and esophageal erosion. They said what I have can cause esophageal cancer . When I stand-up I get dizzy, and my vision goes too bright and dark to see. I am getting an ear ache in my left ear pain in my uperback rib area, troubles swallowing , I get really bad headaches, pressure feeling in my head and jaw, chest pains, and when I use the bathroom my stool is really dark looking not lime usual.
[|AI|]  Hi and welcome to Chat Doctor. Thank you for your query.You should do gastrostomy and rule out esophageal cancer. It can't be just "said". This is serious and it must be treated immediately. SO I don't think you have cancer. You have severe gastritis which could cause ulcer bleeding and dark stool. Your other symptoms can be related to this or caused by anxiety.  SO you must take antacid medicines, follow gastroprotective diet and do frequent gastrostomy check-ups. Wish you good health.
