Frida is fine - as well as can be expected - and is now home. Lots of pain and nausea post surgery, but the pain is more under control now and the nausea has mostly subsided. Surgery went well; the growths don't look cancerous. No new bleeding issues.
Getting there was interesting. As usual, we were in rush to get out the door. After dropping off the kids, we saw the low air pressure indicator go off and were hearing a strange repeating noise. Yep, the tire was punctured and was losing air FAST; a large Allen wrench was jutting out of the tire. Fortunately, we were close to a Discount Tire, so we drove it there. They didn't have the tire in stock, but while I waited for them to put on the spare (which is ridiculously complicated on our mini-van), my dad picked her up to take her to the the hospital, and I fortunately was able to make it up there in time before her surgery.
She came home to a post card from Elizabeth. Thanks!
