Night before last, Daddy had the worst pain he's had since injuring his back. I suspect that if he'd been taking pain meds regularly after his surgery, this wouldn't have happened. He began taking them on a regular schedule yesterday, and today he was much, much better.
I went to visit him and Mom today and had the opportunity to see his two tiny incisions. Each has one tiny stitch; if the stitches weren't there, I'd have had trouble finding the incisions! I'm always amazed by the advances in medicine.
He's still tired, of course, but his pain level seems to have subsided appreciably. I'm very grateful.
