Or at least middle-aged, I guess. Went to the doctor the other day because I'd been having repeated stabbing pains in my knee throughout the day on Tuesday. The NP felt all around the joint, made me move it this way & that, even sent me to x-ray to have pictures taken. Turns out I've got a coupla teeny bone spurs on the bones - arthritis! So now I'm on a 10-day course of mega-Motrin (Rx strength), with knee exercises to do and an ace wrap for the bad days.
I guess I'd suspected arthritis, and I suppose it's good to have an official diagnosis so I know what the problem is, but did I really want to know I've got arthritis? Hmm; maybe not. Denial was a lot easier before the diagnosis. ;)
