Hi, I Had L5-S1 Descectomy 4 Weeks Ago And Am

Hi, I had L5-S1 descectomy 4 weeks ago and am experiencing sciatica pain down both left and right legs with the grabbing pain in my ankles. Before the operation I was experiencing right sicatica pain. I am also experiencing numbness and tingling down both shoulder and arms and feet, with mouth mouth tingling as dropping as well. I have had severe headaches for 10 days which wake me up at night with blurred vision and dizziness. My medical history is I have Multilevel cervical spondylosis, Left paracentral disc osteophyte complex at C6/C7 with possible left C7 compression. My Lumbar spine also has multilevel degenerative change, and did have right paracentral disc bulge at L5/S1 with right S1 Compression, now corrected by surgery. I saw my surgeon yesterday and he has ordered a repeat MRI of cervical and lumbar spine with contrast but I can't get in for that until the 8th of December. to get a MRI done sooner I will have to pay $600 out of pocket. My question is should I do that or wait? Thank you. Christine Bunn
