Well guys I'm pretty drained but the situation is exponentially better now than even before.
My mom (she's 65 BTW, retiring in 10 weeks) was in agony all night with the Vicodin 7.5/500 for which they gave her a prescription. I made sure to pack some Ibuprofen cos I remember when I broke my elbow the docs at the ER gave me a script for that as well as the opiate PK.
I gave her 800mg IB and we gingerly got into the car.
BTW if you ever have a chance to interact with the Cahutauqua Institute or to stay at the Aetheneum hotel, don't hesitate. They were helpful beyond belief. They sent a car to pick her up at the ER, the bellman picked up her script for her, man I cannot stress how well they took care of her.
Anyway we got into the car and started driving and after like 40 minutes she was like, this is amazing. I explained to her that Acetaminophen is an oddball in that it's the only OTC PK that does not reduce swelling as all the other NSAIDS do (it only reduces fever and helps pain). The Ib brought down the swelling, and she could even write with her right hand!
Anyway it's a crime the way they managed her pain. She said even with the Vicodin her pain was 8.5 on a scale of 1 to 10, and after IB it was like 2.5 (when sitting still; moving still hurts).
So we made the trip in 6 hours and I was able to drive smoothly and not upset her too much (I tend to tailgate).
I got her settled at home and we stayed up and watched the end of the Notre Dame game and then the beginning of the NASCAR race. Then my wife and son came over with some special requests for food my mom could eat that was easy to open and eat with one + 1/2 hands. I put a plastic lawn chair in her shower and set up a few more things for her. Just so many little things. She mentioned that she only could drink from a bottle, and needed some Cola to help settle her stomach, and the lady at the front desk without hesitation just handed me $1.75 out of the till to get a bottle of Pepsi from a vending machine.
I looked at the Xrays and she basically broke the bulb at the end of her humerus right off the shaft. Which is lucky cos at least it's just bone and not connective tissue that's damaged (we hope). There is also at least one smaller fragment. She had asked her doctor about "Fosamax" or something which is good for bones. He said "well, we'll see if you need it." Well, guess what, yeah, she needs it.

I told her from now on take a calcium pill for every coffee she drinks.
I put a call into her orthopedist she sees for her knee and he actually called right back! She'll see him on Monday, and my cousin is luckily off Mondays and can take her in. She won't be able to drive for a while.
Man I feel so much more at ease now that I'm able to make her comfortable. It's so heartening to hear her pain went down.
A very draining day and sorry for the long post, just trying to get it off my chest. And thanks for all the well wishes.
