My dad had 3 surgeries on his back. One was fusion of some disks, and one was the titanium shit in his back. On the third surgery, they went in from the front and through the stomach, intestines, etc to work on the back. He almost didn't survive after the surgery. There were blood clots all over the fucking place. Today, he still has major digestive issues.....funny thing, back still sore....but after #3, he aint never going back under the knife.
Although for every horror story I hear on back surgeries, I hear one of someone that is thrilled and pain-free.
In my mind, surgery should be a last resort.
