I have lower back pain which make my legs around my knees ache. I cant set still very long either. I have had shots in my back with nerves burnt. Mr Doctor wants to send me to a spine specialists. Please help I cant sleep at night without my legs kicking. i take medicine for restless leg. But nothing is working.
I think you may be having nerve compression at spine, so it would be better if you see a spine specialist.  He may ask you to get MRI of your spine to check whether you are having nerve compression or not.  If report come positiver than you may to need to take gabapentin and methylcobal tablets. I still consider if nothing comes on MRI than you need to get x-ray of knee if there is some proven with knee that is causing all these issues.
