Sounds like you're a *******! You need to toughen up a bit. Especially if you keep getting hit with wrenches. Then you need to learn how to drive better.
Joking aside! I hope you get better soon! I haven't had a stone removed (yet, fingers crossed) so I can't compare, but I have broke my back and neck. I still feel the pain just about every single day, not kidding. I can count on both hands the number of days I feel really good in a year. At least child birth and this are just temporary. I wish I could have TONS of pain for a few weeks and move on. You should try lots of pain EVERY FU(KIN' day of your life. Seriously, prescription drugs and alcohol keep me going. Sorry I got off on a tangent there, but I do hope you feel better soon.......
