Thanks for all of the replies!

Wilson, you asked:
okay so brooke has been on an antifungal for 4 days ,what dose? and what weight is brooke?
Has brooke started to act any different ?more sick? since you started treatment?
the cysts once open did they heal up? Have they ruled out cancer?
Brooke was on Keto (200 mg 2xday) for 3 full days and now on Itra 140 mg 2xday. Brooke weighs 55 but may have gained a bit back from last weight (couple pounds). Brooke's illness comes and goes. When she started the Keto she was just on the end of feeling quite poorly. She is now eating okay (though I have to cook for her and make it extra yummy right now for her to eat... and she stands there and acts like she is waiting for something different - I just sit down with her until she eats. Feeding several small meals a day. So, she started Keto on a rebound period... I don't think she is feeling better than "almost okay"- she seems a little more down/tired than she would normally during a "good" time... but it is hard to say for sure.
Brooke has not had an open lesion outside of her mouth. She gets lumps (she has had many) small/pencil eraser sized to quarter sized lumps that stay for a week or longer and then just disappear. She did have some lesions in her mouth- kind of large pimplish/boil kind of deals. In her mouth now there is the remains of those lesions but nothing fresh. They don't appear to be draining anything- more like they are in the healing process.
Cancer is a possiblity and has not been ruled out- it would certainly be on the list of things to rule out if we scrape together the funds to get to the university.
On tuesday we have an appt. with vet for a series of xrays (chest/abd) and we will talk again about doing more Tick born illness testing (though I think we have pretty much ruled that out). I am also going to talk to her about going down to the university. My big question for the vet about that is: "Do they want to see Brooke when she is feeling badly? Makes the most sense to me! And if so, how do we go about scheduling that? Once we have the xray appt, and learn what we can from that, I plan to call the U and find out what kind of costs they have/could Brooke be a guinea pig kind of patient etc.
I also talked with Ted's mom (Jen) and learned that Ted was neg for blasto on his urine as was Jen's niece... Jen's hubby tested 0.65 (which is considered negative) but based on symptoms was treated/is being treated for blasto... It is all so confusing.
I wonder if anyone knows what 0.32 means... (aside from being negative) if there is SOME antigen/enough to generate a 0.32, is there not reason to believe there is/could be SOME infection with blasto? How does one have any antigen without some of the blasto inside??
I wonder if I should have another cyst aspirated? If so, what should be done with the aspirated fluid? (First cyst aspirated the vet thought she saw yeast, another sample taken and sent off to a pathologist and pathologist said no blasto)
AAAAHHHHH!
Vet has mentioned this could Addisons- many similar symptoms aside from the fever (105+) and come and go cysts all over her.
Thanks for reading and for caring about us- it is much appreciated!
