Thanks guys. Hopefully I have answers after her appt tomorrow and hopefully they are not the bad answers I don't want to hear.
Her lab work is a little weird. She has glucose in her urine, which normally you would then expect to see a high blood glucose level... but her blood glucose is on the low end of normal (which is typical for her). Because chemo just destroys all sorts of cells, normally she has a low white blood cell count. Today, her WBC count is technically in the normal range, but it is 3x higher than where she's been the past 3 months. So she's trying to fight... something. I didn't do a huge blood panel on her, but what I did check, everything else was normal. Which is good?
She's still not eating and is very lethargic and prefers to just not move. We went to bed last night, she sleeps on the floor next to me. This morning when I got up for work she looked at me, but never got up. She didn't go outside to go potty. When I came home for lunch 6 hours later, she still hadn't moved from that spot. I'm not sure if she's just weak or if she's painful.
She is not vomiting but today when she has asked to go outside, she is out there a looooong time eating grass.
I can sort of make a reasonable case in my head that this could be a severe case of pancreatitis. It's about all I can think of where the glucose in her urine would also fit. The vet I work with is stumped, but she did not think her lab work looked typical of what she'd expect to see if she was coming out of remission. But I'm not sure if she really feels that way or if she just doesn't want to be the bearer of bad news and just wants the oncologist to deal with it.
Sorry for the length, sometimes it's nice to just babble. I'll try to update tomorrow.
Weight gain was not happening for a while, but now all of a sudden she's put on 5 pounds, so just a couple more pounds to go and she'll be back to her normal weight!
