I was having a weekend hell for a few months with my valve. My valve is now on an angle but not enough so to have surgery. They move around. I boil my catheters and then when they are super flexible I insert them, they harden a bit after in there and form their path. So now it goes in a bit better. If it is kinked then you might just have to be taught how to work with the anatomy that way. Most surgeons will not do surgery unless you really need it. If you are gassy that can also have them off a bit. Sometimes if I run then try after blood and gas is moving around it's fine. Stressing on the pot over it will make it worse and cause you to bleed since you are forcing it. It is going to bleed so that isn't to be too alarmed.
