I am sorry you are not well. I know the anxiety and worry can make the symptoms worse. Just cause you have barretts does not mean you are going to get the C word. My sis was dx with barretts in 06. Of course she freaked out and even saw a gastro who specializes in barretts and he said that they make too much of a big deal over the barretts. You know the chances of getting cancer from it are.5%. That is less than 1 in a 100.
In April of 2006 I was dx with HPV from my pap smear. In case you are not familiar HPV is the virus that causes cervical cancer. So now I have to be checked reguarly to make sure cancer does not develop. If something starts to change they can get it out early.
I know people with barretts need to be scoped once a year so if changes start to happen they can take care of it. Its best to know these things so that it can be caught early and treated.
