I've had 3 surgeries over the last 10 years and the pain was less after each one. I didn't even need pain pills after the 2nd day of my last surgery. The only real pain I had was on my hip where they took the bone from for the fusion. As I mentioned though, my surgery was an anterior fusion so there is so will be some differences. I had stiffness, but no real pain. As for showering, for the 1st few days I didn't shower (pew

). I washed my body with a wash rag. To wash my hair I leaned in the tub and had my wife gently wash my hair under the faucet. After a few days I carefully showered without a collar.
