It's a stricture!
Anyone else have this? What was done to resolve the issue? How are you doing now?
Strictures are fairly common especially after having a band with all the scar tissue that builds up underneath the band. I'm surprised that they aren't just dilatating it right off the bat to get rid of it. Why make you suffer more? They don't happen to everybody but they aren't unheard of either. I'm so sorry you are going thru this! At least it is fixable and sometimes they have to dilate it more than once, just so you are prepared. Another thank you to your band!
I know it's not what you wanted to hear, but of all the complications, a stricture is usually the easiest to fix. I'm sure your doc has a reason for wanting to try to resolve it with meds first, but I'd press him a bit on how long you're suppose to wait. The usual fix is a quick dilation, which leads to immediate relief. Some people have to have multiple dilations, but I've never heard of anyone not getting over it.
In the meantime, make sure you don't get dehydrated!
