I get tingling in my legs & feet. Mri says I have L5 problems plus I have lesions on kidneys & liver. I had very bad back pain.?

Leg tingling. The back pain can be caused by muscle strain, spinal stenosis, ruptured disc, nerve impingement ... It sounds like you are experiencing symptoms from nerve impingement. If your pain persists, you should seek help from a health care provider. You might benefit from a comprehensive evaluation and treatment.
See doc. Your L5 problem is it a disk or a lesion - see your doc to rule out neoplasm.
