Yesterday I linked to an image of a mannequin being used to train doctors to do lumbar punctures as an example of one grisly test Karen had done. Now we know that lumbar punctures are just part of the prelim round before they move on to the really, really grisly tests. Today they took some sort of gun that shot a claw into Karen's spine to remove actual tissue for biopsy. I'd link to a picture of a mannequin having that procedure, but it's too painful to use on mannequins.
Because Karen is back in the hospital, I went back to work today. It rained, I was wet, and I had to work for 11 hours, but all in all, no complaints; it was a pretty good day on the claws-into-spine-measure of job satisfaction.
