Re: Please Help!!
this sounds very familiar!!! i have sciatica as the result of my piriformis pinching my nerve, i have si joint pain (no idea what causes that one), and an annular tear in my l3-4. i had 5 mris (with no problems id'd except ddd in my l4-5), but a discogram is what found my problem (the annular tear).
it sounds to me like they're closer to diagnosing the problem than in my case, so a discogram may not be necessary yet. however, if it is a tear or anything like that, he will have to consider the following (at least what i'm aware of - there may be more): idet, fusion, adr, and the like.
in a nutshell - hard to tell, considering you've heard so many causes. if he's like me, though, and has no other diagnostic option left, the discogram may have to be considered. or, maybe shopping for a dr. who can provide more consistency, etc.
wish i could offer more...if steroid shots (i assume they're epidurals?) aren't working, then he may have to consider more serious treatment options. good luck, and please keep us posted when you get more information.
