Numbness & Burning In Some Toes On Right And Left Foot

I have had this condition for about a year now. I've been seeing a podiatrist who has tried everything to relieve this condition. I have had cortisone shots, i've been wearing orthotics, comfortable shoes. I've had an mri on my feet which they found nothing. I also had an mri done on my lumbar spine about a year ago which showed at the l2-3 l3-4 and l4-5 levels, moderate diffuse annular disc bulges and moderate far lateral disc bulge components.. There is compression of the anterior thecal sac and lateral recess regions. These findings are slightly greater on the right l3-4 and l4-5. Also compression of the right descending nerve roots may be present. There is also moderate facet joint and ligamentum flavum hypertropy at l2-3and l3-4. Moderate neural foraminal stenosis is noted at l4-5 bilaterally. Do you think this diagnosis could cause my foot condition? I also have pain down the sides of my legs from the hip area. I would appreciate any feeback you can give me. Thank you.
