I read your previous post, and given the timeframes (you were in the US when it started) it seems unlikely that Giardia is the cause, but, I don't think it's unreasonable to give it a try and see.
[Edit]Sorry I didn't mean to imply you can't get Giardia in the US. I suppose it might be a bit less likely to get here but not at all far fetched. I was actually thinking it was less likely because (what I've read) by most accounts they say the symptoms fade in < 6weeks. Of course, not always! So, if I am to believe what I read, then it would usually clear up (or get better) slowly over time without meds. [/edit]
On the off chance that it is one of those stubborn cases / still a factor (maybe not the only one) it'd be good to have ruled it out prior to surgery. I haven't seen a lot of info on SOD disorders, and I suspect that is because it's usually not diagnosed until they've checked many other things. Part of the issue is in testing and treating it (ERCD I think) there's a fair risk that it'll lead to a bout of pancreatis.
[Edit2] Also, re: celiacs and other allergies, sometime the tests for those are not conclusive, so it's often worth trying an elimination diet for a few weeks to see if conditions improve. Maybe not if you are in awful pain, but, if you are stuck waiting for a diagnosis anyway--I figure why not give it a shot. [/edit]
