Lewis,
Your feelings sound very much like most who have DDD.
The what if factor makes me terrified.
What if I pick the wrong doctor, wrong disc, wrong country, etc?
The conflicts for me are reading the posts.
Some have success and some don't.
There is no real pattern of one disc being better, or doctor.
All have good and bad stories.
I went on Google and just typed in pro disc lawsuits, Texas Back Institute lawsuits, etc. Type any of the discs, doctors, hospitals and lawsuits and that alone will scare off a decision.
Keep reading, keep yourself informed and hopefully we will make the right decision. Oh, and praying helps
