Hi again everyone. Thanks very very much for your concern and suggestions.
Well. So Sunday Kim went to the hospital as early as possible hoping to catch the attending on rounds. Of course, instead the attending didn’t show up until mid-afternoon. The doc, in fairness, did indeed answer all of their questions thoroughly and finally switched up Matthew’s meds to the dreaded Oxycodone and, for when the pain is peaking, Oxycontin. (I guess the differences between the two are like Klonopin vs. Xanax–one is slower to kick in but is extended/continual release and thus lasts longer; the second is faster-acting but shorter-lived. Medical folks, do I have that right?)
The doc also explained the reasons why she believes this is a herniated disk and why an MRI isn’t necessary. She also said that as long as Matthew is continuing to have the pain relatively controlled, he’ll be released on Monday (today). But she added that if Kim/Matthew didn’t feel comfortable with that, there’s an appeals process and they could probably get that extended another day or so. The idea is to get the pain under control until he can begin physical therapy.
Nevertheless, despite the increased confidence, Kim and her mother-in-law (who literally last week had hip surgery–I think I mentioned that earlier in this saga) were able to get a 2nd opinion in the form of the mom-in-law’s orthopedic surgeon. This new doctor–who of course is a specialist–was very helpful and thorough in the examination and explanation, and happily she agreed with the diagnosis and the treatment plan, except (and frankly I cannot believe the original doctor didn’t come up with this) she ordered an anti-inflammatory in addition to the pain meds. (I don’t know if it’s an NSAID or steroids.) The surgeon recommended a spinal expert at the other Columbia Pres. building.
(Frankly I wish he could go to someone much closer to us, particularly at Weill Cornell which is only 10 blocks away. Columbia Presbyterian is about 5 miles away. Why should he have to schlep so far for phys. therapy if he doesn’t have to?)
So that’s basically the update. Matthew was able to take a shower today, and he was definitely in less pain once they began the Oxycodone, although it took longer to kick in (obviously, that’s the point of an extended release). Later once Kim got home, Matthew contacted her and said he was up to watching some Netflix
which Kim took as a good sign, because he does love him some Netflix! (He hasn’t been able to concentrate on anything but the pain since all this started.)
I know Kim’s been writing all this stuff down and I’m going to follow your recommendations to suggest that she write/contact the hospital’s ombudsman regarding the shabby treatment she & Matthew experienced. Holiday weekend or not, there’s no excuse for crap they went through at a hospital with this reputation and caliber.
Anyway. After getting the proper orthopedic surgeon’s diagnosis that yes, it is almost certainly a herniated disc, we’re all feeling a great deal of relief. I started crying just now realizing that as optimistic as I’ve been for Kim’s sake, there’s been a little voice recording in the back of my head whispering bone cancer, bone cancer that I’ve been ignoring because a) part of me knew it was far less likely, but especially b) I didn’t want that thought anywhere in my eyes or voice when I saw or spoke to Kim about this. Getting the second opinion from an expert finally shut down that recording and I didn’t even realize how much tension it’s been causing me all this time.
Helena330, like you, my experience with a large hospital (NY Weill Cornell, as I’ve mentioned) has been terrific, both in the ER as a patient and a family member when my father had his accident. Like DSeid said, it just seems there was some awful breakdown in communications (or lack thereof) and maybe just some super-bad luck regarding the personalities of the nurses/attendants on staff stuck working this weekend.
Sooooo, with a major exhale, I can hopefully avoid having any further rants or diatribes! I know it’ll probably be a long road of recovery ahead for Matthew, and a lot of pressure on Kim, and all I can do is be there for both of them. Luckily we live in the same building so that makes things convenient. 
I know I’m repeating myself but thank you, so incredibly much, to everyone here, particularly ThelmaLou and Helena330 and eclectic wench and all those who’ve stuck with me the longest. It’s been just sucky as hell, but I can’t even express how helpful it is to have such people offering your varied experiences and recommendations and, of course, your encouragement and good wishes.
