Spinal laser surgery

I am a complete coward when it comes to surgery and have never had any surgical procedures carried out. I do however get chronic back pain, and some shoulder and neck problems, and have regular treatment from a chiropractor.
Apparently though, some back pain issues can be treated with spinal laser surgery which is more or less non-invasive although does require some keyhole incision. I certainly do not like the idea of having open surgery on my spine, and would need to be in quite a lot of discomfort to risk it. However, I would be a lot happier with the idea of a simple procedure after which would not leave me laid up in bed for days if not weeks.
