Most patients r very nervous to see a spinal surgeon which is to be expected. However, only 10 percent need surgery and most do well with therapy, injection,and mild medication.In the event there is a need for removal of blockage from a her rated disc or spinal stenosis, less invasive allows much more raid return to activities. More importantly, lower complications. I see so much more comPlications from over use of drugs or excessive injections without a clear diagnosis.I have reviewed the results of over 3000 surgery and pleased to see great progress! Always consider second opinions and do your homework. The Internet is a great resource.
