Well, I'll try to keep it short, but it came down to deep bruising along her side, pulled/strained muscles, possible small fracture rib(s), and (of all things) eating unhealthy food in abundance over the last several days (that's my fault, I'm the chef).
They didn't delve further into the ribs because the doc said that even if they tested further and definitively diagnosed fractures, the treatment would be the same, so they didn't test for that.
Treatment is, stay off your feet (but get up and move around some, too), Tylenol, prescription muscle relaxers, and OTC lidocaine patch over the affected area.
Went in at 6PM, got home at 1AM. She doesn't normally eat lunch, so her last meal was at 10AM. Thankfully, I had my greasy fish, so I was in better shape than she was that way, but still hungry by the time we got home.
Home at 1AM, got things squared away and in bed at 1:30AM...and I had to get up for work at 3AM and haven't been to sleep yet, so we're neither one in a good mood right now.
Thankfully, though, it wasn't anything worse. Now we get to look forward to a fight with the insurance company when they tell us they're not paying because it wasn't an emergency. She had two rounds of lab work for blood, two CT scans (with and without contrast), plus the room fee, doctor's fee, etc...I don't even want to know what that bill is going to be.
