What next!

Hi everybody,
Well the blood tests have proven it........Honey has "masticatory muscle myositis". About a month ago, I noticed Honey having trouble eating. I tried to check in her mouth, and she cried when I tried to open it up. A quick call the the vet, and I took her for a look. Vet was worried that it might be this "disease" and took blood and sent it to a lab somewhere in the U.S. In the meantime, she put Honey on antibiotics, prednisone and tramadol for pain. Tests came back on Friday confirming the diagnosis was accurate. Poor Honey Bunny, she has been thru the wringer in the past year! It was last Nov. that she had the drain put into her head to drain an abcess in her mouth. If a dog can "possibly" be diagnosed with something, then it will be Honey who gets the worst possible scenario. I feel so bad for her but she is much much better now and is able to eat and chew easily. I soften her kibble with hot water and mix it with a half can of wet food. Of course, the prednisone is making her hungry and thirsty! That means out to pee during the night. I don't have the heart to take her water away in the early evening so she might sleep thru the night. She always seems to be so thirsty. The vet is adjusting the dose of pred down so hopefully this won't be an ongoing problem. I love her so much and hope nothing else goes wrong. She's only 2 1/2 years old! Any advice will be appreciated! Thanks for listening...........seems like I never have good news.
