Glad to hear you got the suprapubic tube out.
Yup, this is going to be part of the new normal.
The mucous will be there but it shouldn't be blocking the works to the point of pain.
The mucuos is viscous so it should just pass. Keep up the high intake of water. I suppose if there is enough water in there it will eventually create enough pressure to force it out. I have found mine is less if I just drink water all day, but if I drink ice tea all day it is more. Even crystal lite ice tea does that to me.
You may just want to mention it to the doc (the fact that it got to the point of pain).
The intestines produce mucous as part of their normal function. Just because you have a piece of intestine as a bladder, it doesn't mean that the intestine knows it so it still will do what intestines do.
As Pat said, it does seem to be related to food and drink. I don't know which are better or worse for me. I just know sometimes it is more and other times not.
Just so you know, intestine is not 'sterile' either. So if you wind up on a pirate ship and someone gets a wound, you are not the right guy to pee on the wound anymore. I think that was in one of the Pirates of the Caribbean movies with Johnny Depp.
