I am 45 years old and experiencing lower back and leg pain after 5-10 minutes of standing. Minimally invasive, microdisectomy surgery is suggested for me. I need to know further about treatment options and whether I can postpone the surgery for few months. My MRI report says chronic posterior protrusion of L4 L5 with mild thickening of ligementum flava bilaTerally, cauing mild compression of the thecal sac and severe compression of L5 nerve roots at L4 L5 disc levels. Posterior midline annular tear in L5S1 disc.
