Hi @gungho yes it is fixable, in fact many dialysis patients gets a problem with their fistulas.

It is just mine had lasted this long without any repair. This is actually my second, the first one was about 6 times or so smaller and while it is being operated on I am crying because the surgeon only was using local anesthesia.

The operation had lasted four hours and it traumatized me so I am terrified now in having this one treated. But I will be forced to take it to the surgeon again if it will get more troublesome for me like if it will develop more pain.
