I hope you have got done a MRI lumbar spine to find out the cause of your problem. Without that it would be nearly impossible to find out exactly the reason for your chronic pain . So my advise is get an MRI Lumbar Spine done immediately. Send me the reports and I will guide you if you need General Physician, Orthopaedic , Surgeon or Spine specialist advise. All the best
