welcome to you, i have cd really bad in throat esophogus and cankers, I've had er endoscopies to extract food that got stuck because my throat was swollen, no, my gi said that cd is from mouth to anus, butwhen he scopes me it show not much, but when I started rem that is the first part it helped was my swallowing, it was huge relief, I was afraid to eat only soup or blended stuff, but rem has helped small bowel somewhat not evan near to remission, but the mouthwash is ok but it is for sure bandaid, I found that magic moouth wash works for 10 min's, I gargle with epsom salt and warm water to help heal canker's, the other stuff is just lydocaine. cankers have to heal from your gut, if you know what I mean
