I have a couple more concerns that I hope you all can help with...

I found out yesterday that my comp. carrier is going to dispute my case again (never ending battle). Therefore, I don't expect additional treatment any time soon. Which leads to my first ?:
1) What are the consequences of having to wait for ADR or fusion? Could my disc height decrease to the point that ADR would not be possible? I've also been experiencing tingling in my left foot only. That's been constant for months now. It's not painful but more of an annoyance. Should I be concerned that it could turn into irreversable nerve damage?

2) Is a discogram necessary prior to ADR? It was never suggested that I have one.

3) Is there any risk to your kidneys w/ADR surgery?
