Hello. I would like to know if my spine is stable and if my pain is from my spondylolisthesis. First of all, I am a 40 year old nurse who had an abdominal colpoplexy two months ago. After that surgery, I woke up with sever back pain. It improved for about a week and then I had to go out of town and has only become worse. My doctor says that I am not in jeopardy of more injury if I were to work but may prolong my pain. I am working with PT who says it is not stable enough for me to work as a nurse. I am concerned because I am running out of my FMLA. I have appointments and I am waiting to see a DO and neurosurgeon. I have severe back pain and right leg numbness/tingling, only below the knee. Some burning sensation and rarely sharp pain in my toes. I do have issues with chronic neck pain and DDD. I have had bouts of sciatica and back pain in the past. My MRI 8 years ago showed spondylo grade 1 with bilateral pars defects and some bulging discs. My recent MRI findings are: mild left lumbar curve. Bilateral L5 pars defects are suspected with about 4 mm anterior spondylolisthesis of L5 on S1.There is moderatelL4-L5 disc space narrowing with desiccation. No suspicous marrow replacing lesion. My goal in PT is strengthening my abdominal muscles and pelvic floor. I am doing my exercises in a pool. I have also been having issues with my right SI joint which has been resolving with PT and use of an SI joint stabilizing belt/brace. I appreciate your opinion.
