This morning I got a call from my mom between flights and she heard that he wouldn't need surgery, praise Jesus, but it's three broken vertibrae in his lower back. He'll need to be in a brace for 3 months.
And just now, I talked to my dad!! It was great to hear his voice. His pain is down to a 5 (which I imagine still sucks, but has to be a lot better than a 10!) and they've got him all fitted up with the back brace. He's going in for an x-ray soon to see how the brace is affecting the broken vertebrae. He still doesn't know when they'll let him come home. He hasn't gotten out of bed yet and just got his first meal- mmmmmm hospital food! And he said he was aware of everything the whole time- boy, that had to be terrible.
Anyway, I'm relieved- it could have been so much worse. Thank you all for your prayers- they really work!
