5 yrs ago I was suffering from back pain, for three yrs I tried things from therapy to injections nothing work. 2 yrs ago I had L3,L4 and L5 fusion and I had disc replacement. I swore I would never go through it ever again. But in my recovery, I was in the hospital for 4 days I talked to 3 people that had at least 1 more surgery they called it exploratory surgery just away saying they screwed up and getting away with it. What the doctors don't tell you is the success rate of this surgery. It is ofter misdiagnosis ed 3 months later I was in having that 2nd surgery. I had right leg pain, and numbness from the knee to the ankle after the first surgery they told me it would go away after the 2 surgery healed. In the mean time my right leg kept giving out on me, falling several times. A yr after my last back surgery, I had knee surgery for torn meniscus. My pain level before surgery was a constant 5, now a 8 to a 9. So if your contemplating surgery please check out your doctor and know really what the % of success rate is....Do I regret it ..yes.
