I've had severe low back pain and moderate leg pain (particularly in the left leg) for a year, which stops me from sleeping properly and interferes with my daily activities like walking, studying etc. They found spondylolisthesis grade 1 slip as a result of bilateral pars defects, moderate osteoarthritis of my facet joints, degenerative disc disease in both vertebra and bilateral foraminal stenosis, but more severe on the left side as my nerve has been flattened.
I've exhausted all non-surgical treatments, so when I went back to my doctor he said that my only other options were to put up with it or have spinal fusion surgery. He explained that although he is willing to do the spinal fusion surgery now as I'm in so much pain, he suggested that I think about putting it off for as long as possible because I'm only 16 so obviously having a spinal fusion this early could lead to more problems in the above vertebra, and also that spinal fusion is very successful for treating leg pain but is less successful for back pain, so he was saying that he would prefer to do the surgery when I have more symptoms in my right leg.
It's so frustrating being 16 and not being able to do anything because of the pain, and I really want to have the surgery now but at the same time I don't want to kind of go against what my doctor says, even though he said he is willing to do it. Any advice or has anyone had a similar problem?
