Ooh Ooh! Have to say - I love my vet.
Dr. Glass just called me back. He embroidered upon the Thyroid results, saying the T4 and free T4 levels both came back very low - certainly low enough for him to treat.
He cautioned me against false hope, saying that he doesn't think it will CURE the LarPar, but when I said, "yes, I'd read that although other neuropathies associated with hypothyroid respond to treatment, LarPar doesn't..." he responded with, "Well, that's published, certainly, but it isn't necessarily what we see, clinically" and basically said that there IS a chance that it will improve his symptoms, or at the very least maybe help prevent them from worsening.
I asked if treating the hypothyroid would help prevent megaesophagus, and he said that unfortunately that isn't clear.
And although all of that is lovely, it's not why I said I love my vet! He actually jogs by my house every day, and he said on Sunday since he hadn't reached me on the phone, he considered stopping just to give me the news and let me know that he'd dispensed the medication to the pharmacy, in case I wanted to begin treatment immediately. He finally opted against it, because he was a horrible sweaty mess and he knew he'd speak to me the following day - but still! How many vets do you know would consider swinging by your house to deliver news since they hadn't been able to get you on the phone???
Anyway.
Myasthenia Gravis test results won't be in until Thursday. I'm off to the vet to pick up Pooka's medication!
