and take a biopsy. The strange thing is that the day after this procedure I staring severe pain in my chest and on my back directly across chest pain. The pain is worst when I drink water feels like I'm being stag in my chest. Please help.
You should call the doctor that did your procedure, this is not normal. My son gets endoscopies yearly and has never experienced this. It may not even be related, but regardless call your doctor.
