I am new here and looking for help and info. on what may be causing this. I have 30 years back problems which have slowly progressed past 2 years. Laminectomy at L 4-5 10 years ago for large herniation. Past few years cramping in calves at night, and weakness in lower legs making it hard to walk upstairs or stand very long, and low back pain and swelling SI area. Diagnosed with facet joint arthritis and told leg cramps were caused by low back. Epidurals helped with this in the past. MRI w/contrast one month ago showed 2 bulging disks lumbar area above where I had surgery, one is pinching a nerve. I had 2 injections 13 days ago, one for the disk, one for the arthritis. My symptoms then went from my right leg ( pinched nerve side ) to my left, and back and forth. I thought I was getting slowly better, but while standing yesterday, for about a whole 15 min. I felt both legs from my knees on down, start getting very weak. Within minutes, they were so terribly weak, I had to put my hands on the wall to walk from my kitchen to livingroom as my feet felt like they were going to go through the floor. I had foot drop in BOTH feet so bad I laid down for 2 hours trying dif. positions, nothing worked, I went to hospital and when checked, had no strength at ALL left foot to do anything, R barely any strength. I ended up with steroids for the inflammation still in my low back, meds for the arthritis, a walker, and told to see my doc first thing Mon. This weakness went on from 9 AM to when I went to sleep about midnight. I noticed last night that a certain position on one side with pillow between my legs seemed to relieve pressure and I could move my feet a little better. I am a little better this morning, some strength back, but now my left leg ( opposite side of problem ) is turned way out, low back & buttock pain R side. Does anybody know what would do this? Is this disk herniation or stenosis or what? Ty for any info.
