Kidney troubles

I guess one who is dealing with kidney stones would find the humor in this little cartoon. I sure do!
Tomorrow I'm off to have a stone surgically removed. I've been dealing with 'attacks' for the last week and a half. Each time I've contacted the doctor he's told me that it will pass any time ...only thing is, nobody seems to be telling the stone that! After some pretty intense periods of pain, the dr. has decided that tomorrow morning the stone is to be removed.
Wish me luck!
