Hello Dr. B,
Thank you for your response!
She did have a test for tick borne diseases when they originally were doing the workup that showed elevated PTH which - it was negative. She had a chest Xray about a year ago after her surgery by my vet in TX, and that was negative, though we've not had one since.
Her urine after the Parathyroid surgery was normal and has been since then (we just did a sample this Friday, and I'm waiting for results, as well as a senior panel bloodwork). She's had small amount of crystals in her urine (since she was 5), but I was told that it was most likely from transports to the labs.
I don't think she's had either an Addison's disease test or been tested for diabetes insipidus. Can these tests be done by my local vet?
Becuase she's so sensitive to anesthesias (it takes her at least a week to get back to herself and she never seems to get all the way back), I've been hesitant to do a brain/spinal chord MRI, which was suggested by my vet in Texas after her surgery and before we moved back here to Florida. If they were to find anything, like perhaps a pituitary tumor, or a slipped disc, are there any effective treatments besides surgery? I'm not sure she could handle a surgery, especially after our experience with the last one, and there is always that pesky financial consideration. I'd hate to put her through all that and spend $2k - $3k (which is what I've been quoted for an MRI scan - is that pretty typical?) only to find out she needed another surgery I couldn't afford.
And thank you for your empathy -- it has been hard on us, especially because of the moves and because she's been seen by different teams of people both in TX and here. I've tried to keep careful notes, but I feel like I'm bound to miss something when explaining this to other people.
Thanks for your help. She's a special girl and I appreciate your advice.
