I am a 26 year old male. I was recently diagnosed with grade 1 spondylolisthesis w/ pars fracture. I only have severe leg pain, worse in right leg. I had pins and needles 2 times in the last 4 months, it does not seem to e progressing but its really messing up my quality of life. At first the doctors said they don't want to do surgery because of my age and all, but then after they took an x-ray with me flexing, they suggested surgery. I was wondering what are the chances of my leg pain resolving with conservative therapy? I am terrified to have a spinal fusion and fear the long term consequences. I also want to be 100% sure this is what is causing my problem. Does anyone have any advice? Could this possibly resolve if its unstable? I have been laying in bed for months because I didn't know what was wrong with me and thought I would wake up one day and be fine. What are the chances I will need surgery? Can strengthening core muscles really make me asymptomatic or its a long-shot? I also just realized when I push down on the top of my head it hurts my lower back. The reason I began to think it is a different condition causing my issues is because I just started to develop bi-lateral hand pain that goes up my arm sometimes. I am really scared, does anyone have any input?
