Prayers sent Dan. Has she had any recent gall bladder troubles? I spent 2 weeks in the hospital in 2018 before they finally figured out it was a blood infection called Klebsiella something or other. They have to do a special blood test to find it, by drawing blood from both arms at once and then mixing something in it. I was weak as a kitten and had similar symptoms. That may not be it, but might be worth asking about. They said mine probably came from passing a gall stone thru a bile duct. Hope she gets well soon.
