Seven months ago, I was having problems eating and drinking. I would get this burning feeling and it hurt. If I drank something cold I could feel cold going down my throat as I was drinking. I had an endoscopy and the doctor found three ulcers on my escophagus. I have been on Nexium ever since. Well, I had to be scoped again this Monday to see what was going on and the uclers are gone. I am so happy that I got this problem checked out. According to my doctor, ulcers in your stomach will not cause cancer, but in your escophagus they can if left untreated. So if you are experiencing any problems, please see your doctor to be checked out.
