I didn't have the fracture, but had one bulging disk and one ruptured. L3 was displaced. Much pain initially due to muscle spasms; these died away but I lost a lot of strength in my left leg due to nerves being pinched. L2-L3-L4 were fused and some stenosis cleaned up. I'm all better now (almost three years out).
Note I had been having mild spasms for a few years before the disk gave way. When this happened, there was NO DOUBT what the problem was. Many people have this operation too early, when the cause isn't very apparent. The results in these cases aren't always very good. You're past that point, like me.
Use the drug to carry you until you can get the surgery.
