MRI of lumbar spine, tingling left leg.

I am a 53 years old woman. Please look at the MRI of my lower back and tell me if you see anything that is not normal． For several months, I have been feeling strong internal vibrations (sometimes like tingling electric shocks) in my left leg (starting from my toes to my thigh), which is worse at night, so it is disrupting my sleep. My leg is not visibly shaking externally, though. You cannot see my leg shaking physically. The vibrations were at first tingling sensations in my left leg, but now it became more like internal vibration. I went to doctor and MRIs of brain, neck were quite normal. I also did X-ray of my neck, lower back, and left foot and the doctor didn’t note anything noteworthy. Please look at the MRI of my lower back. Is there anything that could be causing what I’m feeling in my left leg? I still have no diagnosis and my only medication is Vitamin B12 which is not helping. Thank you.
