Amy R -
I have heard that many things can seal a tear (enbrel, DHEA, glucosamine/chondroition/dmso intradiscally, etc....). It is all anectdodal. Until I see some real clinical studies, it is just pot shots from docs who want to make a few more $$$$. Sounds pessimistic I know, but no more docs guessing what "could or might" work.
Nucleo is for contained herniations only. There are no guarentees about annular tears. I have spoke with the med director at Arthrocare, my doc, your doc out in California, and some other nucleo docs. It's only purpose is to decompress any material touching a nerve root. I have a bad feeling about IDET from everything I have read, read on these posts, talked to docs, etc...
I take glucosamin/chondroitin in large (normal) doses thinkin that might help, so far no luck. If I can't find anything, or if SED is not an option, I may end up with another discogram to see exactly how large the tear is. If very small, I'll just have to survive with shots until ADR is more a possiblity.
See what ya think about SED!
