I have been diagnosed with spinal stenosis, spondylolisthesis, degenerative arthritis, degenerative disc disease, to name a few. I had surgery to fix a herniated disc 3 years ago. I had slight nerve damage down my left leg and foot. I have been doing pretty good but recently I am experiencing weakness, slight numbness and tingling down my left leg and foot when I stand and sometimes when I sit. It s not painful. It s weird feeling. It feels like my leg is going to come out from under me. My question is, do you think I have another disc bulging or is this left over from the nerve damage before the back surgery? Thank you for your input.
