I have spinal stenosis which is worsening rapidly. Pain on standing for more than 5-6 min. Extending into front of legs with chronic groin pain more pronounced on left. Poor bladder control. Some sexual dysfunction. Prior laminectomies at L-3,4. Orthopedic surgeon has ruled out hip arthritis. MRI shows impingement on left side at L-5. Have some concerns that this may be turning into CES!
